The synthesis and characterization of the following trimethylphosphine complexes of rhodium and ruthenium are reported; Cl, (A), RhCl(PMe3)3, (B), X, (X = PF6, BPh4), Cl, RhCl(CO)(PMe3)2, Cl, 2, BF4, trans-RuCl2(PMe3)4, 2Cl2 and RuHCl(PMe3)4.The crystal structures of (A) and (B) have been determined by single-crystal X-ray diffraction.Compound (A) is orthorhombic, space group Ccmm with a = 12.366, b = 13.584, c = 12.554 Angstroem, and Z = 4; (B) is triclinic, space group P1- with a = 8.842, b = 8.982, c = 11.825 Angsroem, α = 98.74, β = 92.38, γ = 116.09 deg, Z = 2.The structures were determined using 1476 and 2695 observed intensities measured on an automatic diffractometer and refined to R values of 0.030 and 0.023 for (A) and (B) respectively.The geometries of both the RhP4(1+) cation and RhP3Cl molecule can be described as square planar, with considerable tetrahedral distortion as a result of steric crowding.Rh-P distances in (A) are 2.295 and 2.299(1) Angstroem, whilst in (B) Rh-P bonds trans to each other are 2.295 and 2.296(1) Angstroem, but trans to Cl 2.203 Angstroem; Rh-Cl is 2.410 Angstroem.
