ruthenium-tris(pyrazolyl)methane complexes as potential candidates for cancer chemotherapy agents
abstract
the mecn ligands of complex 1 were substitutionally inert, however, under forcing conditions the dmso ligands of complex 2 were displaced by chelating 1,2-bis(diphenylphosphino)ethane to produce complex 6. structural characterization of compounds 1-8 was performed by nmr spectroscopy, and an x-ray diffraction analysis of complex 7 provided additional evidence for the proposed structures.
