Abstract: The organically templated single crystal of Zn5(PO4)4·H3N(CH2)4NH3 was synthesized by hydrothermal method and its structure was determined by single-crystal X-ray diffraction. Crystal data: orthorhombic, space group Pnma with lattice parameters a=1.834 40(6) nm, b= 1.330 34(4)} nm, c={0^744 97(2)} nm, β=90°, V=1.818 01(9) nm3, Z=4, R1=0.030 9, wR2={0^080 4} . The framework is built up of a network of ZnO4 and PO4 tetrahedra. The Zn4O4 clusters in the compound are linked to PO4 tetrahedra to form basket-shaped building units, which are connected to each other via oxygens, in an alternate up-down manner, to form the three-dimensional architecture.
