By employing 2-( p-fluorophenyl)-1H-imidazole-4,5-dicarboxylic acid( p-FPh H_3IDC) and2,2'-bipy,to react with cadmium( Ⅱ) ion,a new supramolecule [Cd( p-FPh H_2IDC)_2( 2,2'-bipy) ]( complex 1) was successfully synthesized. Complex 1 was characterized by elemental analysis,IR spectroscopy and single crystal X-ray diffraction. In complex 1,the [Cd( p-FPh H_2IDC)_2( 2,2'-bipy) ]units were joined through intermolecular hydrogen bonds to form a 1D chain. Then the 2D sheets were formed by π-π interactions between...
