(3-Methylbenzonitrile-1κN)-cis-tetrakis(μ-N-Phenylacetamidato)-1: 2κ\u3csup\u3e4\u3c/sup\u3e N:O;1:2κ\u3csup\u3e4\u3c/sup\u3e O:N-Dirhodium(II)(Rh - Rh)

The complex molecule of the title compound, [Rh2{N(C 6H5)COCH3}4(NCC7H 7)], has crystallographically-imposed mirror symmetry. The four acetamide ligands bridging the dirhodium core are arranged in a 2,2-cis manner with two N atoms and two O atoms coordinating to the unique RhII atom cis to one another. The Neq - Rh - Rh Oeq torsion angles on the acetamide bridge are 0.75(7) and 1.99(9)°. The axial nitrile ligand completes the distorted octahedral coordination sphere of one RhII atom and shows a nonlinear coordination, with an Rh - N - C bond angle of 162.8(5)°; the N - C bond length is 1.154(7)Å
