The reaction of RuCl2(PPh3)(3) with N-pyrazolylpropanamide (N-ppa) displaces a single PPh3 producing the six-coordinate complex RuCl2(PPh3)(2)(N-ppa) (1). A crystal structure determination of the dichloromethane solvate RuCl2(PPh3)(2)(N-ppa)%26lt;bold%26gt;2%26lt;/bold%26gt;CH2Cl2 (1%26lt;bold%26gt;2%26lt;/bold%26gt;CH2Cl2) 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, RuCl2(PPh3)(2)(N-ppa) molecules are dimerized via N-H%26lt;bold%26gt;%26lt;/bold%26gt;Cl hydrogen bonds. The dimers pack as chains in the c direction and form voids that are occupied by dichloromethane solvent molecules.
