Metal Complexes of Dyes, III[1,2]. - Transition Metal Complexes of Pyrrole Indigo The dianions of octahydroindigo and 4,4′-dibutyl-5,5′-dimethylpyrrole indigo (L) react with metal salts and chloro-bridged complexes [(μ-Cl)M(Cl)PR3]2 (M = Pd, Pt; R = nBu, Et), [(μ-Cl)M(Cl)(η5-C5Me5)]2 (M = Rh, Ir) to give the bis-N,O chelate complexes [M(L - 2H+)]n (M = Cu, Zn), (L - 2H+)[M(Cl)(PR3)]2 (M = Pd, Pt), and (L - 2H+)[M(Cl)(η5-C5Me5)]2 (M = Rh, Ir). The electronic spectra of the soluble complexes with phosphane or C5Me5 ligands show a large bathochromic shift of the absorptions in the visible region compared to the free neutral ligands which is in accordance with PPP calculations of model compounds.
