摘　　要：在水热体系中 ,以 1 ,4 -丁二胺为模板剂制备了 Zn5(PO4 ) 4· H3N(CH2 ) 4NH3单晶 ,单晶结构分析表明 ,该化合物属正交晶系 ,Pnma空间群 ,晶胞参数 a=1 .83 4 4 0 (6) nm,b=1 .3 3 0 3 4 (4) nm,c=0 .74 497(2 )nm,β=90°,V=1 .81 80 1 (9) nm3,Z=4 ,Dc=2 .91 2 Mg· m-3,最终因子 R1=0 .0 3 0 9,w R2 =0 .0 80 4 [I>2 σ(I) ].结构中的锌和磷均与氧形成四面体配位 ,该化合物中含有 Zn4 O4 簇 ,Zn4 O4 簇与 PO4 四面体相连 ,形成了篮子状亚结构基元 。The organically templated single crystal of Zn_5(PO_4)_4·H_3N(CH_2)_4NH_3 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) nm 3, Z=4, R_1=0.030 9, wR_2={0^080 4} . The framework is built up of a network of ZnO_4 and PO_4 tetrahedra. The Zn_4O_4 clusters in the compound are linked to PO_4 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.
