摘　　要：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） nm 3, Z=4, Dc=1^907 Mg/m 3, R1=0.022 9, wR2=0.058 8.A new zinc hydrogen phosphite C_4H_8N_2H_4·Zn(HPO_3)_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.
