(3-Methyl­benzo­nitrile-κN)tetra­kis(μ-N-phenyl­acetamidato)-κ⁴N:O;κ⁴O:N-di­rhodium(II)(Rh—Rh)

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^II atom is five-coordinate, in a distorted pyramidal geometry, while the other is six-coord­in­ate, with a disorted octa­hedral geometry. For the six-coord­inate Rh^II atom, 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 Rh^II atom is coordinated by a trans pair of N atoms and a trans pair of O atoms from the four acetamide ligands. The N_eq—Rh—Rh—O_eq 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].
