Ez. Jandrasics et Fr. Keene, SYNTHESIS AND PROPERTIES OF MONONUCLEAR TRIS(HETEROLEPTIC) OSMIUM(II)COMPLEXES CONTAINING BIDENTATE POLYPYRIDYL LIGANDS, Journal of the Chemical Society. Dalton transactions, (2), 1997, pp. 153-159
A general synthetic methodology has been elaborated for tris(bidentate
ligand)osmium(II) complexes containing three different polypyridyl li
gands. The tris(heteroleptic) complexes were characterized by NMR tech
niques, and the ligand dependence of their electrochemistry and electr
onic spectroscopy examined.
