The title compound, [Rh(C5H7O2)(C18H12Cl3P)(CO)], contains the bidentate acetylacetonate ligand coordinated to the RhIatom, forming a chelate ring [Rh—O = 2.0327 (15) and 2.0613 (14) Å]. The RhIatom is additionally coordinated by one P [Rh—P = 2.2281 (6) Å] and one carbonyl C [Rh—C = 1.812 (2) Å] atom, resulting in a slightly distorted square-planar geometry. The molecules are packed to minimize steric hindrance with the phosphanes positioned above and below the slightly distorted square geometrical plane.

The title compound, [PdCl2{P(C6H11)2(C6H5)}2], forms a monomeric complex with atrans-square-planar geometry. The Pd—P bond lengths are 2.3343 (5) Å, as the Pd atom lies on an inversion centre, while the Pd—Cl bond lengths are 2.3017 (4) Å. The observed structure was found to be closely related to [PdCl2{P(C6H11)3}2] [Grushinet al.(1994).Inorg. Chem.33, 4804–4806], [PdBr2{P(C6H11)3}2] [Clarkeet al.(2003).Dalton Trans.pp. 4393–4394] and [PdCl2P(C6H11)2(C7H7)}2] [Vuotiet al.(2008).Eur. J. Inorg. Chem.pp. 397–407] (C6H11is cyclohexyl and C7H7iso-tolyl). One of the cyclohexyl rings is disordered with the phenyl ring in a 0.587 (9):413 (9) ratio. Five long-range C—H...Cl interactions were observed within the structure.
