通过水热法,以大茴香酸(Hmba=methoxybenzoic acid)、2,2'-联吡啶(bipy)为配体,合成了2个配合物:[Zn(mba)(bipy)(HCOO)]_n (1)和[Cu(mba)(bipy)_2]·2Hmba(2),对其进行了红外光谱、热重分析、单晶X射线衍射和荧光光谱等分析。配合物1属单斜晶系,空间群为P2/c,ZnII离子处在五配位的变形三角双锥环境中。每个HCOO-桥联2个相邻ZnII离子,形成一维链,然后通过氢键作用和芳环间的π-π堆积延伸一维链为三维网络超分子结构。配合物2属三斜晶系,空间群为P1,CuII离子与配位原子构成五配位的变形三角双锥结构。其配合物单元通过芳环间的π-π堆积作用连接为一维超分子链,一维链通过氢键、芳环间的π-π堆积...

The complexes [Zn(mba)(bipy)(HCOO)](n) (1) and [Cu(mba)(bipy)(2)]center dot 2Hmba (2) have been hydrothermally synthesized by Hmba and bipy (Hmba=methoxybenzoic acid,bipy =2,2'-bipyridine, HCOOH=fomic acid). The complexes were characterized by IR spectrum, thermal gravimetric analysis, single crystal X-ray diffraction and fluorescence analysis. The crystal of complex 1 belongs to monoclinic system, space group P2/c. In complex 1, Zn (II) ion is five-coordinated with a distorted trigonal bipyramidal coordination geometry. Each HCOO- ligand bridges two Zn(II) ions, forming a 1D chain. The chains...
