چکیده
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.

The complex molecule of the title compound, [Rh2{N(C6H5)COCH3}4(C6H5CN)2], exhibits crystallographically imposed centrosymmetry. The four acetamide ligands bridging the dirhodium core are arranged in a 2,2-cis manner, with two N atoms and two O atoms coordinating to the unique Rh(II) atom cis to one another. The Neq-Rh-Rh-Oeq torsion angles on the acetamide bridges vary between 1.62 (4) and 1.7...

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-coord-in-ate, with a disorted octa-hedral geometry. For the six-coord-inate Rh(II) atom, the axial nitrile ligand shows a non-linear Rh-nitrile coordination with an...
