Bis(4-hydroxybenzoato-kappa O)bis(nicotin-amide-kappa N)zinc(II)

Abstract

The title compound, [Zn(C6H6N2O)(2) (C7H5O3)(2)], crystallizes as mononuclear molecules with distorted trigonal-bipyramidal zinc coordination. One of the 4-hydroxybenzoate ions is coordinated to zinc as a bidentate ligand, while the other is monodentate. Intermolecular hydrogen bonds between nicotinamide N and carboxyl O atoms, as well as between the nicotinamide O and hydroxybenzoate O atoms, support the molecular packing. Hydrogen bonding of the carboxylate O atoms has an effect on the delocalization in the carboxylate groups.
