摘要

The mol-ecule of the title compound, [Rh(C42H62O3P)(C74H68O4P2]·2.7C7D8, consists of two phospharhodacyclic substructures sharing the Rh atom, which are formed by coordination/ortho-metallation of a triaryl phosphite, and by the coordination of a rigid bis-phosphite, respectively. The metal displays a tetra-hedrally distorted square-planar coordination geometry. A?tert-butyl group shows rotational disorder over two positions with refined site occupancy of 0.561?(3):0.439?(3). Two partial-occupancy toluene solvent mol-ecules are disordered over two orientations with site occupancies of 0.5:0.3 and 0.5:0.4, respectively. Intra-molecular C—H?O hydrogen bonds are observed. In the crystal, complex mol-ecules and toluene solvent mol-ecules pack as alternating layers parallel to the?ac?plane.
