Large uniaxial magnetic anisotropy, expressed by a negative value of the axial zero-field splitting parameter D , has been achieved in a series of trigonal prismatic Co(II) complexes with the general formula [Co(L)X]Y, where L = 1,5,13,17,22-pentaazatricyclo[15.2.2.17,11]docosa-7,9,11(22)-triene, X = Cl- (1a,b), Br- (2), N3 - (3), NCO- (4), NCS- (5), NCSe- (6), and Y = Cl- (1), Br- (2), NCS- (4), NCSe- (5), ClO4 - (3,6). Complexes 1-6 are six-coordinate with the distorted trigonal prismatic geometry imparted by the pentadentate pyridine-/piperazine-based macrocyclic ligand L and by one monovalent coligand X- ...
