Abstract

Electronic absorption spectra of M(CNPh)₆ [M = Cr(0), Mo(0), W(0)], [Mn(CNPh)₆]Cl, and [Mn (CNPh)₆](PF₆)₂ are reported. Each of the M(CNPh)₆ complexes exhibits three intense metal-to-ligand charge transfer (MLCT) absorption bands between 20.8 and 32.7 kK. The lowest MLCT bands are observed at 29.9 and 31.1 kK in the electronic spectrum of Mn (CNPh)₆⁺. Low energy bands at 18.2 and 20.4 kK in [Mn(CNPh)₆]²⁺ are assigned to vibronic components of a σ(CNPh) → dπ charge transfer transition. The unique electronic structural properties of arylisocyanide complexes are apparently related to the π conjugation of aromatic ring orbitals with the out-of-plane π*(CN) function.
