摘要 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 new metal-organic complex {[Cd(pam)(en)2].H2O}n(1)(H2pam = pamoic acid,en = ethanediamine) has been synthesized in hydrothermal condition.Crystal data of complex 1: Orthorhombic,Fddd,a=17.3706(17) ,b=24.197(2) ,c=25.901(2) ;α=β=γ= 90°,V= 10886.5(18) 3,Z= 16.X-ray diffraction indicates that Cd(II) has the coordinated number of six and pamoic acid acts as the bridge ligand to form 1D chain structure.The 3D porous network is constructed due to hydrogen bond between the chains and uncoordination water molecules.Complex 1 posseesses good thermostability.The fluorescence spectrum indicates that complex 1 have favourable fluorescence under ultraviolet light.
