Ruthenium Compounds

“…In addition, magnetic measurements conducted for the complexes [Ru 2 (O 2 CMe) 3 (bpnp)]PF 6 and Ru 2 (meonp) 4 show room temperature magnetic moments of 2.79 and 2.51 BM, respectively, which are consistent with the presence of two unpaired electrons. 173,174 These structural and magnetic data give support to the 2 4 2 * 2 * 2 electronic confi guration.…”

Mono and dinuclear complexes of half-sandwich platinum group metals (Ru, Rh and Ir) bearing a flexible pyridyl-thiazole multidentate donor ligand

“…p * transition in the ultraviolet region and metal-to-ligand charge transfer (MLCT) dp(M) ? p * (L -ligand) bands in the visible region [69]. Since the low spin d 6 configuration of the mononuclear complexes provides filled orbitals of proper symmetry at the Ru(II), Rh(III) and Ir(III) centers, these can interact with low lying p * orbitals of the ligands.…”
