Description
In the title compound, [Rh2(C8H8NO) 4(C8H7N)], the four acetamidate ligands bridging the dirhodium core are arranged in a 2,2-trans manner. One Rh IIatom is five-coordinate, in a distorted pyramidal geometry, while the other is six-coordinate, with a disorted octahedral geometry. For the six-coordinate RhIIatom, the axial nitrile ligand shows a non-linear Rh-nitrile coordination with an Rh-N-C bond angle of 166.4 (4)° and a nitrile N-C bond length of 1.138 (6) Å. Each unique RhIIatom is coordinated by a trans pair of N atoms and a trans pair of O atoms from the four acetamide ligands. The Neq-Rh-Rh-Oeq torsion angles on the acetamide bridge varies between 12.55 (11) and 14.04 (8)°. In the crystal, the 3-methylbenzonitrile ring shows a π-π interaction with an inversion-related equivalent [interplanar spacing = 3.360 (6) Å]. A phenyl ring on one of the acetamide ligands also has a face-to-face π-π interaction with an inversion-related equivalent [interplanar spacing = 3.416 (5) Å].
