Bis(isonicotinamide-kappa N-1)bis[4-(methylamino)benzoato]zinc(II) monohydrate

Abstract

In the title Zn-II complex, [Zn(C8H8NO2)(2)(C6H6N2O)(2)]center dot H2O, the Zn atom is coordinated by two 4-methylaminobenzoate (MAB) and two isonicotinamide (INA) ligands in a distorted trigonal-bipyramidal geometry; one of the MAB ions acts as a bidentate ligand while the other MAB and the two INA are monodentate ligands. The dihedral angles between the carboxyl groups and the adjacent benzene rings are 8.52 (22) and 5.10 (14)degrees. In the crystal, intermolecular O-H center dot center dot center dot O and N-H center dot center dot center dot O hydrogen bonding links the molecules into a supramolecular structure. Weak intermolecular C-H center dot center dot center dot O interactions are also present.
