Abstract top

The title compound, [Rh(C10H7N2O2)(C18H15P)(CO)]·(CH3)2CO, is the second structural report of a metal complex formed with the O,O'-C10H7N2O2 (neocupferrate) ligand. In the crystal structure, the metal centre is surrounded by one carbonyl ligand, one triphenylphosphine ligand and the bidentate neocupferrate ligand, forming a distorted square-planar RhCO2P coordination set which is best illustrated by the small O-Rh-O bite angle of 77.74 (10)°. There are no classical hydrogen-bond interactions observed for this complex.

Comment top

The title compound (Figure 1) forms part of a series of rhodium complexes used in the kinetic studies of oxidative addition reactions (Basson et al., 1984, 1986; Steyn et al., 1992; Smit et al., 1994; Roodt & Steyn, 2000).

In the crystal structure, the Rh(I) metal centre is coordinated to one carbonyl ligand, one triphenylphosphine ligand and the bidentate neocupferrate ligand, (C10H7N2O2) to form a distorted square planar complex best illustrated by the small O–Rh–O bite angle of 77.74 (10) °. The Rh–O2 bond length of 2.026 (3) Å is significantly smaller than the Rh–O3 bond length of 2.082 (2) Å and is indicative of the larger trans-influence of the PPh3 ligand as opposed to the carbonyl ligand. This is the second structural report involving the neocupferrate ligand (Tamaki & Okabe, 1998). There is no classical hydrogen interaction observed for this complex.

Experimental top

A solution of [Rh2Cl2(CO)4] was prepared by refluxing a solution of hydrated RhCl3 in DMF for approximately 30 minutes. An equivalent amount of N-hydroxy-N-nitrosonaphtylamine (neocupf) was added to this solution to produce [Rh(neocupf)(CO)(PPh3)], which was isolated through precipitation with water. The title compound was obtained by leaving a 5 cm3 beaker containing a concentrated acetone solution of [Rh(neocupf)(CO)(PPh3)] uncovered at room temperature. Well shaped yellow crystals formed within 4 h.

Refinement top

The methylene, aromatic and methyl H atoms were placed in geometrically idealized positions (C—H = 0.93 – 0.98 Å) and constrained to ride on their parent atoms with Uiso(H) = 1.2Ueq(C) for methylene and aromatic protons and Uiso(H) = 1.5Ueq(C) for methyl protons, respectively. The highest residual electron density was located 0.99 Å from H4A and the deepest hole was 0.85 Å from Rh1.

Special details top

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
