The structure was characterized by elemental analysis, IR spectroscopy and X ray single crystal diffraction. X ray single crystal analysis reveals the structure consists of [La(C8H6NO2)3]n. It crystallizes in monoclinic crystal system with space group P2(1)/c.

This compound has one-dimensional anionic chains containing four-membered rings built from corner-sharing linked alternating ZnO4 tetrahedra and HPO3 pseudo pyramids. The zinc hydrogen phosphite chains are interacted with the templates of diprotonated piperazine by N—H…O hydrogen bond.
