Joanne L Stewart, Anne K Bentley, Adam R Johnson, Chip Nataro, Barbara A Reisner, Lori A Watson
For many who passed through his classroom, Richard Andersen demonstrated how inorganic chemistry can be taught by incorporating the research literature. The Interactive Online Network of Inorganic Chemists (IONiC) through its website and summer workshops for faculty has supported the development and sharing of more than a hundred exercises or "learning objects" derived from articles highlighting research across the inorganic field. Faculty can adapt and implement these learning objects in their own classrooms to achieve goals such as demonstrating historical context, teaching course material via current research, and elaborating on the scientific process...

Reinhard Hoy, Peter Lönnecke, Evamarie Hey-Hawkins
The tridentate phosphine ligand 1,3,5-tris[(E)-(4-phospholano-2,6-diethyl)styryl]benzene (1) reacts with [AuCl(tht)] (tht = tetrahydrothiophene) independent of the stoichiometry employed with selective formation of a two-dimensional coordination polymer (ratio 1 : 1) with the gold(i) cations in a trigonal-planar [3 + 1] coordination geometry. Each of the three coordinating phosphine units originates from another ligand, thus forming a polymeric structure.

Novel N6-coordinated Ir(iii) complexes bearing polypyridyl ligands were synthesized and characterized. In comparison to their Ru(ii) analogs, these Ir(iii) complexes showed blue-shifted UV-vis absorption and emission spectra, but dramatically increased triplet lifetimes with much broader and stronger triplet excited-state absorption.

Jun Ohata, Zachary T Ball
As a rare element with no known natural biological function, rhodium has a limited history in biological chemistry and chemical biology. However, rhodium complexes have unique structure and reactivity attributes, and chemists have increasingly used these attributes to probe and perturb living systems. This brief review focuses on recent advances in the use of rhodium complexes in biological contexts, including medicinal chemistry, protein science, and chemical biology. In particular, we highlight both structure- and reactivity-driven approaches to biological probes and discuss how coordination environment affects molecular properties in a biological environment...

The apatite-like NaLa9(GeO4)6O2:Nd3+,Ho3+ phosphor is prepared using the solid-state method. Rietveld refinement of high-resolution time-of-flight neutron powder diffraction measurements indicate that this compound crystallizes in the hexagonal system with space group P63/m, Z = 1 and unit cell parameters a = 9.88903(6) Å, c = 7.25602(5) Å, V = 614.521(7) Å3 at room temperature. The 4f sites are statistically occupied by La, Nd and Na, while 6h sites are occupied by La and Nd. Luminescence in the near- and middle-IR range caused by the transitions in neodymium and holmium ions is excited under 808 nm laser diode radiation...

Ajeet Singh, Shaikh M Mobin, Pradeep Mathur
The synthesis of pyridine alcohol based ruthenium carbonyl clusters Ru3(hep)2(CO)8 (1), Ru3(hpp)2(CO)8 (2), and Ru3(bhmp-H)2(CO)8 (3) {hep-H = 2-(2-hydroxyethyl)pyridine, hpp-H = 2-(3-hydroxypropyl)pyridine and bhmp-H2 = 2,6-bis(hydroxymethyl)pyridine} has been carried out by the reaction of the corresponding pyridine-alcohol ligands with Ru3(CO)12. Clusters 1-3 have been characterized using elemental analysis, NMR, FT-IR, mass spectrometry and single-crystal X-ray structures. The clusters were explored for the selective catalytic transformation of primary amines into secondary amines using alcohols as the mono-alkylating agents via hydrogen transfer reactions...

We report a detailed study of the structure of the [Bi(DO3A)] complex both in the solid state and in solution. The X-ray crystal structure of [Bi(DO3A)] evidences the octa-coordination of the Bi(iii) ion, which is directly coordinated to the four nitrogen atoms of the cyclen unit and three oxygen atoms of the carboxylate groups. The octa-coordination is completed by an oxygen atom of a neighboring carboxylate group, which bridges Bi(iii) ions thanks to μ2-η1:η1 coordination, resulting in the formation of a coordination polymer...

Structurally characterised two polymeric complexes of Cu(ii) (3) and Mn(iii) (4) of the ligand L (2-(((2-(phenylamino)ethyl)imino)methyl)phenol) have been explored for catecholase-like activity, fluorescence recognition of histidine and catalytic activity towards coupling of aryl iodides with benzamide, leading to N-arylbenzamides. CuO nano-cubes (NCs) prepared by thermal decomposition of the Cu(ii) complex function as photocatalysts for the degradation of methylene blue. Cube-like morphology of CuO nanocrystal and flake-shaped micrometer order Cu(ii) complex have been established from the field emissive scanning electron microscopy (FESEM) images...

A new mononuclear Ni(ii) complex, [NiL] (1) of an unsymmetrically dicondensed N2O2 donor ligand, H2L (where H2L = N-α-methylsalicylidene-N'-salicylidene-1,3-propanediamine), has been synthesized. Complex 1, on reaction with Mn(ii) in the presence of different co-anions, yielded three heterometallic NiII-MnII complexes, [(NiL)2Mn(NCS)2]·CH3CN (2), [(NiL)2Mn(N3)(H2O)](ClO4)·H2O (3) and [{(NiL)2Mn(H2O)}2(μ1,3-N3)](ClO4)3 (4). Single crystal structural analyses show that complexes 2 and 3 contain similar bent trinuclear NiII2MnII structures, with the difference that in complex 2 two SCN- ions and in 3, one N3- and one H2O molecule are coordinated to the Mn(ii) centre...

Two positional isomers, 4-methyl-2-((quinolin-6-ylimino)methyl)phenol (6-QMP) and 4-methyl-2-((quinolin-2-ylimino)methyl)phenol (2-QMP), have been synthesized to compare their fluorescence sensing properties. 6-QMP and 2-QMP have been synthesized by Schiff-base condensation between 2-hydroxy-5-methylbenzaldehyde and the respective amine (6-aminoquinoline for 6-QMP and 2-aminoquinoline for 2-QMP) under mild conditions. These compounds have been characterized by standard methods. 6-QMP and 2-QMP have been found to be dual fluorescence chemosensors for Al3+ and Zn2+ ions but the increment of fluorescence intensity varies...

The double-tartaric bridging Tm-substituted POM derivative [N(CH3)4]6K3H7[Tm(C4H2O6)(α-PW11O39)]2·27H2O (1) was successfully synthesized and well characterized by various physico-chemical analyses. Furthermore, the mixed Dy3+/Tm3+ ion-based POM derivatives [N(CH3)4]6K3H7[DyxTm1-x(C4H2O6)(α-PW11O39)]2·27H2O (3-8) were first synthesized and confirmed by PXRD and IR spectra, indicating compounds 3-8 are isomorphic with 1. The detailed analyses of Ln-O-W bond angle and coordinated aqua ligands around emitting Ln3+ ions have revealed that the mentioned negative factors do not effectively affect the luminescence of emitting Ln3+ ions in 1-8...

All the products were fully characterized by using various analytical techniques and their molecular structures were determined by X-ray crystallography.

A series of color-tunable NaBa1-zSrzB9O15:Ce3+,Mn2+ phosphors were synthesized by a high temperature solid state method. Luminescence property, energy transfer, thermal stability and cation substitution were investigated in detail. Due to energy transfer, NaBaB9O15:Ce3+,Mn2+ presents violet to green luminescence and manifest a broad excitation range from 200 to 350 nm. The energy transfer mechanism of Ce3+-Mn2+ is identified as a dipole-dipole interaction. NaBa1-zSrzB9O15:Ce3+,Mn2+ displays both Ce3+ violet and Mn2+ green and orange emissions under ultraviolet excitation...

The synthesized ceramic phosphors were investigated by X-ray diffraction (XRD), scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS), photoluminescence (PL), radioluminescence (RL) and thermoluminescence (TL) analyses. CdTa2O6:Eu3+ phosphors exhibited emissions at 591.8 nm and 612.1 nm because of the characteristic band transitions of the Eu3+ ion. Phosphor emission increased with increasing Eu3+ ion dopant up to 1...
