Abstract: A new zinc hydrogen phosphite C4H8N2H4·Zn(HPO3)2 was prepared by hydrothermal method in the presence of piperazine as a structure-directing agent and the crystal structure was determined by single-crystal X-ray diffraction analysis and further characterized by X-ray powder diffraction, IR, ICP, elemental analysis and TG analysis. 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. Crystal data for C4H8N2H4·Zn(HPO3)2;monoclinic, space group C2/c. a=1.774 8(2) nm, b=0.724 28(9) nm, c=0.880 87(11) nm, β= 105.345(3)°, V=1.091 9(2) nm3, Z=4, Dc=1.907 Mg/m3, R1=0.022 9, wR2=0.058 8.
