Two novel copper
and cadmium complexes with 2-methylimidazole (2-meim) and 2,2¢-dimethylglutarate (dmg2-) as ligands, [Cu2(m-dmg)2(2-meim)4]∙5H2O (1) and {[Cd(m-dmg)(2-meim)2]∙H2O}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 (CuO2N2) while Cd(II) ions
showed a distorted octahedral geometry (CdO4N2). 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
complex 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.
