摘要
水热合成了一个新配合物{[Cd(BDC)(bpimb)0.5(H2O)]·H2O}n。通过元素分析、红外光谱、热重以及X-射线单晶洐射对其进行了表征.该晶体属单斜晶系,P21/c空间群。Cd髤原子通过BDC和bpimb两种配体连接成一维带状结构,带与带之间通过O-H…O和C-H…O连接成三维超分子结构。室温下配合物具有较强的荧光发射光谱。
A novel one-dimensional cadmium(Ⅱ) complex {[Cd(BDC)(bpimb)0.5(H2O)]·H2O}n(1) with phthalic acid(H2BDC) and 1,4-bis((2-(pyridin-2-yl)-1H-imidazol-1-yl)methyl)benzene(bpimb) has been synthesized by means of hydrothermal method and characterized by elemental analysis,IR spectrum,thermal analysis and single-crystal X-ray diffraction.The crystal is of monoclinic,space group P21/c with a=1.591 9(3) nm,b=0.689 23(14) nm,c= 2.229 5(3) nm,β=126.882(10)°,V=1.956 6(6) nm3,Dc=1.727 g·cm-3,Z=4,F(000)=1 020,Goof=1.070,R1=0.049 4,wR2=0.101 9.Complex 1 shows a novel one-dimensional(1D) ribbon structure and further extended into a 3D supramolecular structure through O-H … O and C-H … O hydrogen bonding interactions.Luminescent studies show that complex 1 exhibits intense blue fluorescent emission.CCDC:768901.
