Tetra-kis[µ-N-(2,4,6-trimethyl-phen-yl)acetamidato]-κ4N:O;κ4O:N-bis-[(benzo-nitrile-κN)rhodium(II)](Rh-Rh).

The title structure, [Rh2(C11H14NO)4(C7H5N)2], contains a dinuclear Rh complex of point symmetry -4 with an Rh-Rh unit and two benzonitrile ligands located in special positions along the twofold axis passing through -4. Four symmetry-equivalent mesitylacetamidate ligands bridge the Rh-Rh unit. Thus, each Rh(II) atom has an approximately octa-hedral coordination by one Rh [Rh-Rh = 2.4290 (6) Å], two acetamidate O atoms trans to each other [Rh-O = 2.044 (3) Å], two acetamidate N atoms trans to each other [Rh-N = 2.091 (4) Å], and a benzonitrile N atom trans to Rh [Rh-N = 2.222 (3) Å]. The structure is held together by weak van der Waals forces.
