Description:
Crystals of the title compound, [HgI2(C18H14N4O2)] n , were obtained by the reaction of HgI2 and p-phenylene-bis(pyridine-3-carboxamide) in DMF. The asymmetric unit is composed of only half of the formula unit; the mercury atom lies on a crystallographic twofold rotation axis, and there is an inversion centre at the centre of the benzene ring. Each HgII atom is coordinated by two I atoms and two N atoms from two p-phenylene-bis(pyridine-3-carboxamide) (bpfb) ligands, in a distorted tetrahetral geometry. Bpfb acts as a bifunctional bridging ligand, linking HgII atoms into a one-dimensional chain. Hydrogen-bonding interactions between the O atom and the H atoms of bpfb ligands result in a two-dimensional supramolecular network.
