Interaction of 2-methyl imidazole with tetraaquoadipatocobalt(II) polymer in water-ethanol mixture yielded dimeric cobalt(II) complex[Co(COO-(CH2)4-COO) (C4N2H6)2]2·H 2O. The complex has been characterized by elemental analysis, IR spectroscopy and single crystal X-ray diffraction techniques. The crystal structure contains a dimer consisting of two Co(cis-2Melm) units joined by two molecules of a folded dibasic acid forming an 18 membered ring. The metal center possesses a highly distorted octahedral geometry comprising two N-atoms from two 2-methylimidazoles and four O-atoms form two adipate anions forming strained four membered chelate rings. The molecule has a center of symmetry and forms a through channel with the maximum and minimum dimensions of 8.25(7) A and 5.27(2) A respectively. The hexagonally close packed dimeric units along a-axis includes a water molecule in the exterior channel.
