| Abstract: | Metal Complexes of Dyes. X. New Transition Metal Complexes of Anthraquinone Dyes The chloro-bridged compounds (R3P)MCl2]2 (M ? Pd, Pt; R ? ethyl, phenyl, n-butyl), (Ph3P)2PdCl]2(BF4)2, (η5-C5Me5)MCl2]2 (M ? Rh, Ir), (η6-p-cymene)RuCl2]2,  react with mono- and dianions of several 9,10-anthracene-dione dyes 1-amino-9,10-anthracene-dione, Disperse Blue 19 (1-amino-4-anline-9,10-anthracene-dione), 1,4-diamino-9,10-anthracene-dione, Solventgreen 3 1,4-bis(4′-methylaniline)-9,10-anthracene-dione], dianthrimide 1,1′-dianthraquinonylamin], 1-azo-β-naphtol-9,10-anthracene-dione, 1-anilido-o-carboxy-9,10-anthracene-dione and Quinizarin (1,4-dihydroxy-9,10-anthracene-dione)] to give N,O-, O,O- and O,N,O-chelate complexes. Copper(II)- and palladium(II) acetate and the anion of 1-aminoanthraquinone afford N,O-bischelates. Spectroscopic data are discussed. In comparision to the free anthraquinones the dye complexes show a bathochromic shift in the UV/VIS spectra. The structures of (ethyl)3P(Cl)Pt(1-aminoanthraquinone-H+), (η-C5Me5)(Cl)Ir(1-azo-β- #naphtolanthraquinone-H+) and (η-C5Me5)Rh(1-anilido-o-carboxyanthraquinone-2 H+) were determined by X-ray diffraction. |
