Crystal structures of fac-trichloridotris(trimethylphosphane-κP)rhodium(III) monohydrate and fac-trichloridotris(trimethylphosphane-κP)rhodium(III) methanol hemisolvate: rhodium structures that are isotypic with their iridium analogs

Abstract

The crystal structures of two solvates of fac-trichloridotris(trimethylphosphane-κP)rhodium(III) are reported, i.e. one with water in the crystal lattice, fac-[RhCl3(Me3P)3]·H2O, and one with methanol in the crystal lattice, fac-[RhCl3(Me3P)3]·0.5CH3OH. These rhodium compounds exhibit distorted octahedral coordination spheres at the metal and are isotypic with the analogous iridium compounds previously reported by us [Merola et al. (2013). Polyhedron, 54, 67–73]. Comparison is made between the rhodium and iridium compounds, highlighting their isostructural relationships.
