(Acetyl-acetonato-κ(2)O,O')[(2-bromo-phen-yl)diphenyl-phosphane-κP]carbonyl-rhodium(I).

In the title compound, [Rh(C(5)H(7)O(2))(C(18)H(14)BrP)(CO)], the Rh(I) atom adopts a slightly distorted square-planar geometry involving two O atoms [Rh-O = 2.077†(2) and 2.033†(2)†à ] of the acetyl-acetonate ligand, one carbonyl C atom [Rh-C = 1.813†(2)†à ] and one P atom [Rh-P = 2.242†(5)†à ] of the PPh(2)(2-BrC(6)H(4)) phosphane ligand. Difference electron density maps indicate a disorder of the Br atom over two positions in an approximate 0.95:0.05 ratio. However, this disorder could not be resolved satisfactorily with the present data.
