The reaction of RuCl 2 (PPh 3 ) 3 with N ‐pyrazolylpropanamide ( N ‐ppa) displaces a single PPh 3 producing the six‐coordinate complex RuCl 2 (PPh 3 ) 2 ( N ‐ppa) ( 1 ). A crystal structure determination of the dichloromethane solvate RuCl 2 (PPh 3 ) 2 ( N ‐ppa) · 2CH 2 Cl 2 ( 1·2CH 2 Cl 2 ) revealed that the geometry about the central Ru atom is distorted octahedral with the chloride ligands in trans ‐position and the N ‐ppa acting as N , O ‐chelating ligand. In the solid state, RuCl 2 (PPh 3 ) 2 ( N ‐ppa) molecules are dimerized via N–H ··· Cl hydrogen bonds. The dimers pack as chains in the c direction and form voids that are occupied by dichloromethane solvent molecules.
