MU-[(2-BROMOPHENYL)-(O-PHENYLENE)PHENYLPHOSPHINE-C P]-TRICYCLOHEXYLPHOSPHINEDIRHODIUM(II)/

The single-crystal X-ray structure determination of the title compound , enyl-C1:P2}-tricyclohexylphosphine-P)dirhodium(II) (Rh-Rh)-trichloro methane solvate, [Rh2(mu-C2H3O2)3(mu-C18H13BrP) (C18H33P)].CHCl3, is r eported. Space group P1 was established and the absolute configuration of the title compound was assigned. The Rh2(4+) coordination geometry is defined by three bridging acetates, one monometallated triphenylph osphine and one axial tricyclohexylphosphine. The Rh(1) coordination g eometry is octahedral, while Rh(2) is pentacoordinated. The Rh(1)-Rh(2 ) distance is 2.4769 (1) angstrom. The Rh(2)...Br(1) intermolecular di stance is 3.669 (1) angstrom.
