Synthesis and crystal structure of a trihydrate of dinuclear benzimidazole-2-pyridinecarboxylate- cadmium(II)

Abstract

A new compound, [Cd₂(C₇H₆N₂)₃(C₆H₄O₂N)₄]·₃H₂O (1), has been prepared under mild hydrothermal conditions and structurally characterized by single crystal X-ray diffraction. The two cadmium(II) ions are bridged by a carboxyl group from one 2-pyridinecarboxylate ligand. The thermal gravimetry (TG) data indicate three steps of decomposition, and the final thermal decomposition product is CdO.
