Electronic Transitions in Different Redox States of Trinuclear 5,6,11,12,17,18-Hexaazatrinaphthylene-Bridged Titanium Complexes: Spectroelectrochemistry and Quantum Chemistry.

ABSTRACT: Multinuclear transition metal complexes bridged by ligands with extended π-electronic systems show a variety of complex electronic transitions and electron transfer reactions. While a systematic understanding of the photochemistry and electrochemistry has been attained for binuclear complexes, much less is known about trinuclear complexes such as hexaphenyl-5,6,11,12,17,18-hexaazatrinaphthylene-tristitanocene [(Cp₂ Ti)₃ HATN(Ph)₆ ]. The voltammogram of [(Cp₂ Ti)₃ HATN(Ph)₆ ] shows six oxidation and three reduction waves. Solution spectra of [(Cp₂ Ti)₃ HATN(Ph)₆ ] and of the electrochemically formed oxidation products show electronic transitions in the UV, visible and the NIR ranges. Density f
