On the short carbonyl bond in bis[μ-1, 2-benzisothiazol-3(2H)-one 1, 1-dioxido-κ2N: O] bis([1, 2-benzisothiazol-3(2H)-one 1, 1-dioxido-κN]-bis(imidazole)copper(II))

Abstract

The short carbonyl bond in the title compound, [Cu2(C7H4NO3S)4 (C3H4N2)4] [Liu, Huang, Li & Lin (1991). Acta Cryst. C47, 41-43], is an artifact of disorder in the isothiazol-3(2H)one 1, 1-dioxide part of the 1, 2-benzisothiazol-3(2H)-one entity. In the present redetermination, all bond dimensions in the centrosymmetric dinuclear molecule are normal. The five-coordinate Cu atom shows trigonal-bipyramidal coordination. Hydrogen bonds from the imidazole donor ligand link adjacent molecules into a two-dimensional layer structure.
