Abstract :Two novel copper and cadmium complexes with 2-methylimidazole (2-meim) and 2,2 ¢ -dimethylglutarate (dmg 2- ) as ligands, [Cu 2 ( m -dmg) 2 (2-meim) 4 ]∙5H 2 O (1) and { [Cd( m -dmg)(2-meim) 2 ]∙H 2 O} n ( 2 ), have been systematically synthesized and characterized. The result in organic-inorganic crystalline solid. Their solid-state structures have been solved with elemental analysis, IR spectroscopy, and the single-crystal X-ray diffraction. The Cu(II) ions distorted square planar geometry (CuO 2 N 2 ) while Cd(II) ions showed a distorted octahedral geometry (CdO 4 N 2 ). Complex 1 is dimeric structure, in which Cu(II) ions were bridged by dmg ligand. These dimeric units are extended to the 3D supramolecular structure with hydrogen bonding, C–H∙∙∙ p , C–O∙∙∙ p and p ∙∙∙ p interactions. The c omplex 2 is 1D polymeric structure, where Cd(II) ions are connected by bis(bidentate) dmg ligands to form 1D zig-zag polymeric chains which are further extended in 3D supramolecular structure through hydrogen bonding, C–H∙∙∙ p and C–O∙∙∙ p interactions. The thermal properties of the complexes were investigated.Keywords : 2-methylimidazole ligand, Cu(II) complex, Cd(II) complex, Coordination polymers, Supramolecular
