Synthesis and molecular structure of monomeric copper (II) acetates with 2-methylimidazole and 1, 2-dimethylimidazole

Abstract

The complexes cis-bis(acetato)bis(2-methylimidazole)copper(II) (1), and cis-bis(acetato)bis(1,2-dimethylimidazole) copper(II) (2) have been prepared by the reaction of the appropriate imidazole derivative with copper(II) tetraacetate. The complexes have been characterized by analytical, magnetic, spectroscopic and crystallographic methods. Complex 1 crystallizes in the orthorhombic space group P212121 and has unit cell dimensions of a=7.5380(10), b=7.7100(10), c=26.310(5) Å. Complex 2 crystallizes in the monoclinic space group P2/c and has unit cell dimensions of a=15.574(2), b=7.9520(10), c=14.752(2) Å.
