Description

The complex molecule of the title compound, [Rh2{N(C6H5)COCH3}4(C8H7N)2], exhibits inversion symmetry. The four acetamidate ligands bridging the dirhodium core are arranged in a 2,2-trans manner with two N atoms and two O atoms coordinating to each RhIIatom trans to one another. The Neq - Rh - Rh - Oeq torsion angles on the acetamidate bridge vary between -4.07 (5) and -6.78 (7)°. The axial nitrile ligands complete the distorted octahedral coordination sphere of each RhIIatom and show a nonlinear coordination with Rh - N - C bond angles of 151.6 (3) and 152.5 (3)°. The bond lengths of the two nitrile triple bonds are 1.133 (5) and 1.137 (5) Å.
