Abstract

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 RhII atom has an approximately octahedral 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.
