The Synthesis and Characterization of a Supramolecular Compound { Cd( H_2dtca)( bipy) }

A new supermolecular compound { Cd2( H2dtca)2( bipy)2} [H2dtca = 1,3-di( 2',4'-dicarboxypheny)-benzene,bipy = 2,2'-bipyridine]was synthesized hydrothermally and characterized by means of elemental analysis, IR and single crystal X-ray diffraction. Complex crystallizes in monoclinic space group P21 / n,a = 1. 604 06( 7) nm, b = 1. 037 30( 4) nm,c = 1. 720 97( 7) nm; β = 101. 803 0( 10) °; Z = 4,wR1= 0. 034 2,wR2= 0. 079 5. The crystal structure of compound revealed that one 1,3-di( 2',4'-dicarboxypheny) benzene ligand links two CdIIions to form a symmetrical dimmer,and the binuclear units form a 3D supramolecular structure under the action of the hydrogen bonds. The luminescence property in solid state of complex have been further studied and discussed in this paper.
