采用水热法合成了一种过渡金属镉配合物{[Cd(pam)(en)2].H2O}n(1)(H2pam=pamoic acid,en=ethanediamine)。该晶体属于正交晶系,Fddd空间群,晶胞参数为:a=17.3706(17),b=24.197(2),c=25.901(2);α=β=γ=90°,V=10886.5(18)3,Z=16。Cd(II)中心原子具有六配位的八面体结构,H2pam作为桥连配体与金属配位构成了一维的链状结构,链之间通过和未配位的游离水形成氢键(O—H…O)构成具有孔道结构的三维超分子网络结构。化合物1具有良好的热稳定性。荧光光谱分析结果表明,在紫外光的激发下化合物1有良好的发光特性。
A transition metal cadmium complex {[Cd (pam) (en) 2] .H2O} n (1) (H2pam = pamoic acid, en = ethanediamine) was synthesized by hydrothermal method. The crystal belongs to the orthorhombic, Fddd space group with unit cell parameters of a = 17.3706 (17) , b = 24.197 (2) and c = 25.901 (2) ; V = 10886.5 (18) 3, Z = 16. The central atom of Cd (II) has a hexacoordinated octahedron structure. H2pam, as a bridged ligand, coordinates with the metal to form a one-dimensional chain structure. Hydrogen bonds (O -H ... O) form a three-dimensional supramolecular network structure with pore structure. Compound 1 has good thermal stability. Fluorescence spectrum analysis showed that Compound 1 has good luminescence properties under UV excitation.
