Abstract

The reaction between C6H4-1,3-(CH2PCy2)2, Cy = cyclohexyl, and RhCl3·3H2O produced trans-[RhCl2(OH2) {C6H3-2,6-(CH2PCy2)2}], [RhCl2(OH2)(PCP)]. The product was characterised spectroscopically and the crystal and molecular structure of its 2-propanol solvate, [RhCl2(OH2)(PCP)·propan-2-ol, C35H61Cl2O2P2Rh, as determined by X-ray analysis. The crystals are monoclinic, space group P21/a, with A = 11.513(1), B = 25.874(2), C = 13.576(1) î.., β = 113.47(6)°, V = 3709.7(3) î..3, M = 749.71, Z = 4. Comparisons with other rhodium-aqua complexes show that the Rh---O distances are extremely sensitive to trans influence, but sensitive to other factors such as the oxidation state or coordination number of the metal ion, or steric crowding. The charge on the complexes appears to exert only a minor influence.
