title: Bis(μ-nitrito-κ(2)O:O)bis-[bis-(1-methyl-1H-imidazole-κN(3))(nitrito-κO)copper(II)].
abstract: In the binuclear title compound, [Cu(2)(NO(2))(4)(C(4)H(6)N(2))(4)], centro-symmetric-ally related complex mol-ecules are linked via weak Cu-O inter-actions, forming dimeric units. The Cu(II) atom displays an elongated square-pyramidal CuN(2)O(3) coordination geometry with a slight tetra-hedral distortion of the basal plane [maximum deviation = 0.249 (2) Å]. The dihedral angle formed by the imidazole rings is 26.20 (10)°.
