The crystal structure of Zn2 (HPO4) 3 · H3NCH2 CH2 NH3 was prepared from non-aqueous system, and the crystal structure was determined by X-ray diffraction. The compounds were characterized by IR and DTA-TG. (3) nm, c = 0.9760 (3) nm, α = 93 .8 (3) °, β = 95.3 8 (3) °, γ = 10.975 (3) °, V = 0.63 94 nm3, Z = 2, Dc = 2.50 g · cm- 3. Both zinc and phosphorus in the structure are formed with oxygen Tetrahedral coordination, Zn O4 and HPO4 tetrahedra are arranged strictly alternating, the oxygen in the skeleton is divided into two bridge oxygen and end oxygen, the end oxygen only to the P atom coordination three-dimensional open skeleton structure in the a-axis and b-axis direction There are 12-membered straight channels, protonated organic amines in the a-axis direction of the twelve-membered ring channel
