Crystal structure and Hirshfeld surface analysis of aqua-bis-(nicotinamide-?N1)bis-(2,4,6-tri-methyl-benzoato-?O)zinc.


ABSTRACT: The asymmetric unit of the title complex, [Zn(C10H11O2)2(C6H6N2O)2(H2O)], 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 R22(12), R33(10) and R33(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.
