The enthalpies of reaction of [(p-cymene)RuCl2]2 (p-cymene = (CH3)2CHC6H4CH3) with a series of N-substituted tertiary phosphine ligands, leading to the formation of (p-cymene)-RuCl2(PR3) complexes (PR3 = tertiary phosphine) have been measured by solution calorimetry in CH2Cl2 at 30°C. The overall relative order of stability, within this series, is as follows: P(NC4H4)3 4H4)2(C6H5) 4H4)(C6H5)2 4H8)3. Structural studies have been performed on three complexes in the (p-cymene)RuCl2(PR3) system, PR3 = P(NC4H4)3, P(NC4H4)2(C6H5), and PBz3. Thermochemical and structural data are compared to provide an understanding of the bonding involving these N-pyrrolyl-substituted phosphine ligands.
