Résumé
A general approach for the prepn. of dinuclear ?5- and ?6-cyclic hydrocarbon platinum group metal complexes, viz. [(?6-arene)2Ru2(NN?NN)Cl2]2+ (arene = C6H6, 1; p-iPrC6H4Me, 2; C6Me6, 3), [(?5-C5Me5)2M2(NN?NN)Cl2]2+ (M = Rh, 4; Ir, 5), [(?5-C5H5)2M2(NN?NN)(PPh3)2]2+ (M = Ru, 6; Os, 7), [(?5-C5Me5)2Ru2(NN?NN)(PPh3)2]2+ (8) and [(?5-C9H7)2Ru2(NN?NN)(PPh3)2]2+ (9), bearing the bis-bidentate ligand 1,2-bis(di-2-pyridylaminomethyl)benzene (NN?NN), which contains two chelating di-pyridylamine units connected by an arom. spacer, is reported. The cationic dinuclear complexes have been isolated as their hexafluorophosphate or hexafluoroantimonate salts and characterized by use of a combination of NMR, IR and UV-vis spectroscopic methods and by mass spectrometry. The solid state structure of three derivs., [2][SbF6]2, [3][PF6]2 and [4][PF6]2, has been detd. by x-ray structure anal. [on SciFinder(R)]
