Abstract
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 mol-ecule is composed of two Rh(I) cations, the tetra-dentate dianion α,α'-bis-(salicylaldiminato)-m-xylene and two 1,5-cyclo-octa-diene (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-enanti-omers of one another. The intra-molecular Rh⋯Rh distance of 5.9432 (3) Å suggests that there is no direct metal-metal inter-action.
