四种新型的镧系配位聚合物[Pr(mal)(OH)(bipy)·2 H2O]n(1),{[Dy 1(SBA)3(H2O)2][Dy 2(SBA)3(H2O)2]·4 H2O}n(2),{[Tb(OHnic)(Onic)(H2O)5·(OHnicH)]·H2O}n(3)和{[Sm(OHnic)(Onic)(H2O)5·(OHnicH)]·H2O}n(4)合成了顺丁烯二酸(Hmal=马来酸,HSBA=4-磺基苯甲酸,OHnicH=6-羟基烟酸,bipy= 2,2 ′-联吡啶)的配合物,并用X-射线单晶衍射法测定了配合物的结构。配合物1是一个一维螺旋链,具有七个配位的Praseo-benzene中心。配合物2为一维链状分子结构,其中Dy 1为七配位,Dy 2为八配位。同晶配合物3和4通过桥连Onic 2 −阴离子的羟基氧原子连接相邻的中心离子,呈现出前所未有的一维链状聚合结构,结构单元中存在三种稀土羧酸配合物中罕见的6-OHnicH配体。利用紫外吸收光谱、荧光激发光谱和发射光谱研究了配合物的物理化学性质。
Four novel lanthanide coordination polymers [Pr(mal)(OH)(bipy)·2H2O]n(1), {[Dy1(SBA)3(H2O)2][Dy2(SBA)3(H2O)2]·4H2O}n(2), {[Tb(OHnic)(Onic)(H2O)5·(OHnicH)]·H2O}n(3) and {[Sm(OHnic)(Onic)(H2O)5·(OHnicH)]·H2O}n(4) (Hmal=maleic acid, HSBA=4-sulfobenzoic acid, OHnicH=6-hydroxynicotinic acid and bipy=2,2′-bipyridine) have been synthesized and determined by single crystal X-ray diffraction. Complex 1 is a 1-D helical chain with seven-coordinated praseodymium centers. Complex 2 forms 1-D chain-like molecular structure containing two crystallographically unique dysprosium centers, the Dy1center is seven-coordinated while Dy2is eight-coordinated. The isomorphous complexes 3 and 4 exhibit an unprecedented 1-D chain-like polymeric structure through hydroxyl oxygen atoms of bridging Onic2−anions linking up the neighboring central ions, and there exist three types of 6-OHnicH ligands in the structural unit which is rare for lanthanide carboxylate complexes. The photophysical properties of these complexes were studied using ultraviolet absorption spectra, fluorescence excitation and emission spectra.
