Özet
In the title compound, [CuCl(2)(C(11)H(15)N(3)O(2))], the Cu(II) ion is five-coordinated in a strongly distorted trigonal-bipyramidal arrangement, with the two methyloxime N atoms located in the apical positions, and the pyridine N and the Cl atoms located in the basal plane. The two axial Cu-N distances are almost equal (mean 2.098 A) and are substantially longer than the equatorial Cu-N bond [1.9757 (15) A]. It is observed that the N(oxime)-M-N(pyridine) bond angle for five-membered chelate rings of 2,6-diacetylpyridine dioxime complexes is inversely related to the magnitude of the M-N(pyridine) bond. The structure is stabilized by intra- and intermolecular C-H...Cl hydrogen bonds which involve the methyl H atoms, except for one of the two acetylmethyl groups.
