μ(2)-m-Xylylenebis(salicylaldiminato)-bis­(η(4)-1,5-cyclo­octa­diene)dirhodium(I) dichloro­methane solvate

In the title solvate, [Rh(2)(C(22)H(18)N(2)O(2))(C(8)H(12))(2)]·CH(2)Cl(2), each organometallic mol­ecule is composed of two Rh(I) cations, the tetra­dentate dianion α,α′-bis­(salicylaldiminato)-m-xylene and two 1,5-cyclo­octa­diene (COD) ligands. Each Rh(I) atom is coordinated by one O atom [Rh—O = 2.044 (2) and 2.026 (2) Å], one N atom [Rh—N = 2.083 (2) and 2.090 (2) Å], and one COD ligand via two η(2)-bonds, each directed toward the mid-point of a C=C bond (Cg): Rh—Cg = 2.007 (2), 2.013 (2), 2.000 (2) and 2.021 (2) Å. Each Rh(I) atom has a quasi-square-planar coordination geometry, with average r.m.s. deviations of 0.159 (1) and 0.204 (1) Å from the mean planes defined by Rh and the termini of its four coordinating bonds. The two COD ligands have quasi-C (2) symmetry, twisted from ideal C (2v) symmetry by 30.0 (3) and −33.1 (3)°, and are quasi-enanti­omers of one another. The intra­molecular Rh⋯Rh distance of 5.9432 (3) Å suggests that there is no direct metal–metal inter­action.
