Deskripsi
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 RhII atom 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 RhII atom 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.
