Heterometallic complexes derived from ruthenocene-functionalized dipyrromethenes

Abstract A new ligand based on a ruthenocene moiety appended by a diyrromethene (Rc-dpm) was synthesized. Two copper complexes, Cu(Rc-dpm) 2 ( 3 ) and Cu(Rc-dpm)acac ( 4 ), and one cobalt complex, Co(Rc-dpm) 3 , 5 , were prepared from the ligand. These complexes were characterized by a combination of UV–Vis spectroscopy, elemental analysis, and X-ray crystallography. Copper(II) complex 3 was found to be coordinated by two dipyrromethene ligands in a distorted square planar environment around the copper while complex 4 had one dipyrromethene ligand and an acac coordinated in a nearly idealized square planar copper geometry. The cobalt(III) complex 5 has an octahedral geometry around the cobalt via the coordination of three dipyyromethene ligands.
