Evidence for Bidirectional Noninnocent Behavior of a Formazanate Ligand in Ruthenium Complexes
Original language description
Redox series of the complexes [Ru(L)(L)2]n, L = 1,5-diphenyl-3-(4-tolyl)-formazanate and L = 2,4-pentanedionate (acac-), 2,2-bipyridine (bpy), or 2-phenylazopyridine (pap), were studied by cyclic and differential pulse voltammetry and by TD-DFT-supportedspectroelectrochemistry (UV-vis-NIR, EPR). The precursors [RuIII(L-)(acac-)2], [RuII(L-)(bpy)2]ClO4, and [RuII(L-)(pap)2]ClO4 were identified in their indicated oxidation states by X-ray crystal structure determination. The six-membered formazanato-ruthenium chelate rings have an envelope conformation with puckering of the metal. DFT calculations indicate a pronounced sensitivity of the N-N bond lengths toward the ligand oxidation state. Several electrochemically accessible charge states were analyzed,and the derived oxidation numbers RuII, RuIII, or RuIV, L or (L)-, and L-, L2-, or the new formazanyl ligand L for the two-way noninnocent formazanate reflect the increasing acceptor effect of the ancillary ligands L in the series acac-
