Bis(1H-imidazole-κN)bis-(2-methyl-benzoato-κO)bis-(2-methyl-benzoic acid-κO)copper(II).

ABSTRACT: The structure of the title compound, [Cu(C(8)H(7)O(2))(2)(C(3)H(4)N(2))(2)(C(8)H(8)O(2))(2)], consists of centrosymmetric monomeric units, in which the Cu(II) atom has a tetra-gonally distorted octa-hedral coordination involving two imidazole N atoms and two carboxyl-ate O atoms in the square plane [Cu-N = 1.964 (3) and Cu-O = 1.960 (2) Å] and 2-methyl-benzoic acid O atoms in axial sites [Cu-O = 2.753 (3) Å]. Within the complex, the carb-oxy-lic acid forms intra-molecular O-H⋯O hydrogen bonds, while the mol-ecules are assembled through N-H⋯O(carbox-yl) hydrogen bonds into chains extending along the a-axis direction. These chains are further linked by weak π-π inter-actions [centroid-centroid separation = 3.930 (2) Å].
