Crystal and molecular structure of potassium bis(dimethylphenylphosphine)bis(dithiocarbonato)rhodate(III) trihydrate

Abstract

The structure of the title compound (II), K[Rh(S₂CO)₂(PMe₂Ph)₂]·3H₂O has been determined. Crystals are monoclinic, space group P2₁/c, with a= 18.798, b= 6.516, c= 23.924 Å, β= 113.91°. There are two independent anions per unit cell with crystallographic C_i() symmetry. They are essentially identical, and the planar dithiocarbonate ligands have Rh–S 2.37, C–S 1.725, C–O 1.25 Å; S–Rh–S 73.5, S–C–S 111, and S–C–O 125°.
