Abstrakt: A hydridoruthenium(II) complex [RuClH(CO)(PPh3)3] reacted easily with acrylonitrile and fumaronitrile to give chloro-bridged binuclear (1-cyanoethyl)ruthenium(II) complexes, [{Ru(MeCHCN)Cl(CO)(PPh3)2}2] (2) and [{Ru(NCCH2CHCN)Cl(CO)(PPh3)2}2], respectively. Complex 2reacted with 4-picoline (pic), Na[BHPz3] (Pz=1-pyrazolyl), Na[BPz4], and Na[Et2NCS2]·3H2O to afford the corresponding (1-cyanoethyl)ruthenium(II) complexes, [{Ru(MeCHCN)Cl(CO)(pic)(PPh3)}2] (3), [Ru(MeCHCN)(BHPz3)(CO)(PPh3)] (accompanied by a small amount of [Ru2(MeCHCN)2Cl(BHPz3)(CO)2(PPh3)4]), [Ru2(MeCHCN)2Cl(BPz4)(CO)2(PPh3)2], and Na[Ru(MeCHCN)Cl(Et2NCS2)(CO)(PPh3)], respectively. Complex 3reacted with thallium(I) acetylacetonate [Tl(acac)], resulting in the formation of [{Ru(MeCHCN)(acac)(CO)(PPh3)}2] and [Ru(MeCHCN)(acac)(CO)(pic)(PPh3)]. These new complexes were characterized by means of elemental analysis and spectroscopic data. The diastereoisomerism was also discussed as regards these (1-cyanoethyl)ruthenium(II) complexes.
