Crystal structure and Hirshfeld surface analysis of aquabis(nicotinamide-κN1)bis(2,4,6-trimethylbenzoato-κ2O,O′)cadmium(II)
[摘要] The asymmetric unit of the title complex, [Cd(C10H11O2)2(C6H6N2O)2(H2O)], contains one half of the complex molecule, with the CdII cation and the coordinated water O atom residing on a twofold rotation axis. The CdII cation is coordinated in a bidentate manner to the carboxylate O atoms of the two symmetry-related 2,4,6-trimethylbenzoate (TMB) anions and to the water O atom at distances of 2.297 (2), 2.527 (2) and 2.306 (3) Å to form a distorted pentagonal arrangement, while the distorted pentagonal–bipyramidal coordination sphere is completed by the two pyridine N atoms of the two symmetry-related monodentate nicotinamide (NA) ligands at distances of 2.371 (3) Å in the axial positions. In the crystal, molecules are linked via intermolecular N—H⋯O, O—H⋯O and C—H⋯O hydrogen bonds with R22(12), R33(8), R33(14), R33(16), R33(20), R33(22), R44(22), R55(16), R66(16) and R66(18) ring motifs, forming a three-dimensional architecture. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are H⋯H (56.9%), H⋯C/C⋯H (21.3%) and H⋯O/O⋯H (19.0%) interactions.
