Abstract: Single crystal of Zn2(HPO4)3·H3NCH2CH2NH3 was synthesized from nonaqueous system and its crystal structure was determined using single crystal X-ray diffraction. The crystal structure was solved by direct method and refined by full-matrix least-square method and the crystal is triclinic, space group P1 with a =0.8215(3) nm, b =0.8557(3) nm, c =0.9760(3) nm, α =93.8(3)°, β =95.38(3)°, γ =109.75(3)°, V =0.6394 nm3, Z =2, Dc=2.50 g·cm-3 , μ =43.0 cm-1 , R =0.031, Rw=0.040. The framework is built up from ZnO4 and HPO4 tetrahedra, forming a three dimensional network, and the linkage of Zn and Ptetrahedra displays a strict alternation of zinc and phosphorus. The open framework contains 8-membered ring channels and 12-membered ring channels. The results of XRD, IRand DTA-TGfor the compound are given.
