Synthesis and Structure of Dicarbonyldichloro{2-(Diphenylphosphineoxide)pyridine}ruthenium(ii)

Abstract

Reaction of the dinuclear complex [{Ru(CO) 3 Cl 2 } 2 ] with the ligand 2-(diphenylphosphineoxide)pyridine (PyPOPh 2 ) in ethanol solution gave the neutral mononuclear complex [Ru(k 2 -PyPOPh 2 -N,O)(CO) 2 Cl 2 ]. The complex was characterized by elemental analysis, IR and RMN spectroscopy, and its molecular structure was determined by single-crystal X-ray diffraction.
