title: Di-μ-nitrito-κO:O-bis-[bis-(1-ethyl-1H-imidazole-κN)(nitrito-κO)copper(II)].
abstract: In the structure of the title compound, [Cu(2)(NO(2))(4)(C(5)H(8)N(2))(4)], the asymmetric unit consists of two moieties containing one Cu ion, two nitrite ions and two 1-ethyl-1H-imidazole mol-ecules associated via weak Cu-O inter-actions. Each Cu(II) atom displays an elongted square-pyramidal CuN(2)O(3) coordination geometry with a slight tetra-hedral distortion in the basal plane. The dimeric units are linked into a three-dimensional network by C-H⋯O hydrogen bonds.
