Abstract
Single-crystal X-ray diffraction studies were conducted bn the following co mpounds: Cp*Ru(PMe3)(2)Cl (1), Cp*Ru(PPhMe2)(2)Cl (2), Cp*Ru(PMePh2)(2)Cl ( 3), Cp*Ru(PPh3)(2)Cl (4), Cp*Ru(PEt3)(2)Cl (5), Cp*Ru(AsEt3)(2)Cl (6), Cp*R u((PBu3)-Bu-n)(2)Cl (7), and Cp*Ru(dmpm)Cl (8). Structural information obta ined from these X-ray studies can be correlated with enthalpies of ligand s ubstitution previously determined from solution calorimetry. The cone angle of the phosphine ligand (monodentate) and the Ru-P bond distance were foun d to be proportional to the enthalpy of reaction.
