Tetraaquabis[N,N′-bis(pyridin-3-ylmethylidene)benzene-1,4-diamine]zinc dinitrate 1.49-hydrate

Abstract

In the title compound, [Zn(C18H14N4)2(H2O)4](NO3)2·1.49H2O, the ZnII atom, lying on an inversion center, is coordinated by two N atoms from two N,N′-bis(pyridin-3-ylmethylidene)benzene-1,4-diamine ligands and four water molecules in a distorted octahedral geometry. The nitrate anion is disordered over two sets of sites, with an occupancy ratio of 0.744 (4):0.256 (4). The uncoordinated water molecule is also disordered with an occupancy factor of 0.744 (4). O—H...O and O—H...N hydrogen bonds link the complex cations, nitrate anions and uncoordinated water molecules into a supramolecular layer parallel to (102).
