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

ABSTRACT: The title structure, [Rh?(C??H??NO)?(C?H?N)?], 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 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 eac ...[more]

(3-Methyl-benzo-nitrile-κN)tetra-kis(μ-N-phenyl-acetamidato)-κ(4) N:O;κ(4) O:N-di-rhodium(II)(Rh-Rh).

Project 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(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 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 Neq-Rh-Rh-Oeq torsion angles on the acetamide bridge varies between 12.55 (11) and 14.04 (8)°. In the crystal, the 3-methyl-benzo-nitrile ring shows a π-π inter-action with an inversion-related equivalent [inter-planar spacing = 3.360 (6) Å]. A phenyl ring on one of the acetamide ligands also has a face-to-face π-π inter-action with an inversion-related equivalent [inter-planar spacing = 3.416 (5) Å].
