Crystal structure and Hirshfeld surface analysis of aqua-bis-(nicotinamide-κ N 1 )bis-(2,4,6-tri-methyl-benzoato-κ O )zinc.

The asymmetric unit of the title complex, [Zn(C10 H11 O2 )2 (C6 H6 N2 O)2 (H2 O)], contains one half of the complex mol-ecule, and the ZnII cation and the water O atom lie on a twofold rotation axis. The ZnII cation is coordinated by two carboxyl-ate O atoms of the two symmetry-related 2,4,6-tri-methyl-benzoate (TMB) anions and by the water O atom at distances of 2.0311 (16) and 2.076 (2) Å to form a slightly distorted trigonal-planar arrangement, while the distorted trigonal-bipyramidal coordination sphere is completed by the two pyridine N atoms of the two symmetry-related monodentate nicotinamide (NA) ligands at distances of 2.2066 (19) Å in the axial positions. In the crystal, mol-ecules are linked via inter-molecular N-H⋯O and O-H⋯O hydrogen bonds with R 2 2 (12), R 3 3 (10) and R 3 3 (16) ring motifs, forming a double-column structure running along the c -axis direction. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (58.4%), H⋯C/C⋯H (20.3%) and H⋯O/O⋯H (18.3%) inter-actions.
