Abstract
Two new complexes, {[Cd(bimt)(bdc)(H 2O)]·2H 2O} n ( 1) and [Cd(bimt)(Hbtc)] n ( 2) have been synthesized through the self-assembly of Cd(NO 3) 2·4H 2O with unsymmetrical N-heterocyclic ligand 2-((benzoimidazol-yl)methyl)-1H-tetrazole (bimt) and aromatic polycarboxylate acid 1,3-benzenedicarboxylic acid (H 2bdc) or 1,3,5-benzenetricarboxylic acid (H 3btc). Single crystal X-ray diffraction determination shows that complex 1 possesses an infinite 2-D layered structure with parallelogram grid units. Complex 2 is a 2-D layered structure containing 1-D ladder-like chains linked by the Hbtc 2− anions in tridentate bridging fashion. Both complexes are stacked into complicated 3-D frameworks by coordinating bonds and hydrogen bonds in the solid state. In addition, the luminescent properties of both complexes have been investigated in the solid state at room temperature.
