摘要：
Reaction of [Ru(COD)Cl-2](x) (COD = 1,5-cyclooctadiene) with pyridine-2,6-dicarboxylic acid (dipicH(2)) in the presence of Et3N afforded an anionic complex [Et3NH][(dipic)(COD)RuCl] (1) with a kappa(3)-dipic coordination mode. Treatment of 1 with AgNO3 in MeOH/H2O afforded a neutral complex [(dipic)(COD)Ru(H2O)] (2) in a high yield. Reaction of 2 with 1 equiv. of L gave the according adducts [(dipic)(COD)Ru(L)] (L = py (py = pyridine, 3), 4-t-Bupy (4), NH3 (5), t-BuNH2 (6), PhCH2NH2 (7), and MeCN (8)), while the similar reaction with 0.5 equiv. of 4,4'-bipyridine afforded a binuclear complex [{(dipic)(COD)Ru}(2)(mu-bipy)] (bipy = 4,40-bipyridine, 9). All complexes have been spectroscopically characterized along with the electrochemical analyses, and the structures of complexes 1-4, 7 center dot MeOH and 9 center dot 2H(2)O have been also determined by single-crystal X-ray diffraction.
