摘要：
Complexes of the formulae [(eta(5) -C5H5)Ru(PPh3)(C5H5N-2-CH = N-C6H4-p-X)](+) [X = H (2a), CH3 (2b), OCH3 (2c), Cl (2d), NO2 (2e)] and [(eta(5)-C5H5)Ru(PPh3)(C5H5N-2-CH = N-C6H11)](+) (3) were prepared by reacting para-substituted N-(pyrid-2-ylmethylene)-phenylamines(2-PP) and N-(pyrid-2-ylmethylene)cyclohexylamine (2-PC) with [(eta(5)-C5H5)Ru(PPh3)(2)Cl] (1) in methanol. These complexes have been isolated as hexa-fluorophosphate salts. Representative complex 2e has been established by single crystal X-ray diffraction analysis. Complex 2c crystallizes in the orthorhombic space group P-bcn, with a = 21.1560 (11) Angstrom, b = 18.3972 (9) Angstrom and c = 17.5130 (9) Angstrom, V = 6816.3 (6) Angstrom(3) and z = 8. All these complexes were characterized by FT-IR, H-1 NMR and P-31{H-1} NMR spectroscopy. (C) 2004 Elsevier Ltd. All rights reserved.
