A hydridoruthenium(II) complex [RuClH(CO)(PPh<SUB>3</SUB>)<SUB>3</SUB>] reacted easily with acrylonitrile and fumaronitrile to give chloro-bridged binuclear (1-cyanoethyl)ruthenium(II) complexes, [{Ru(MeCHCN)Cl(CO)(PPh<SUB>3</SUB>)<SUB>2</SUB>}<SUB>2</SUB>] (<B>2</B>) and [{Ru(NCCH<SUB>2</SUB>CHCN)Cl(CO)(PPh<SUB>3</SUB>)<SUB>2</SUB>}<SUB>2</SUB>], respectively. Complex <B>2</B> reacted with 4-picoline (pic), Na[BHPz<SUB>3</SUB>] (Pz=1-pyrazolyl), Na[BPz<SUB>4</SUB>], and Na[Et<SUB>2</SUB>NCS<SUB>2</SUB>]·3H<SUB>2</SUB>O to afford the corresponding (1-cyanoethyl)ruthenium(II) complexes, [{Ru(MeCHCN)Cl(CO)(pic)(PPh<SUB>3</SUB>)}<SUB>2</SUB>] (<B>3</B>), [Ru(MeCHCN)(BHPz<SUB>3</SUB>)(CO)(PPh<SUB>3</SUB>)] (accompanied by a small amount of [Ru<SUB>2</SUB>(MeCHCN)<SUB>2</SUB>Cl(BHPz<SUB>3</SUB>)(CO)<SUB>2</SUB>(PPh<SUB>3</SUB>)<SUB>4</SUB>]), [Ru<SUB>2</SUB>(MeCHCN)<SUB>2</SUB>Cl(BPz<SUB>4</SUB>)(CO)<SUB>2</SUB>(PPh<SUB>3</SUB>)<SUB>2</SUB>], and Na[Ru(MeCHCN)Cl(Et<SUB>2</SUB>NCS<SUB>2</SUB>)(CO)(PPh<SUB>3</SUB>)], respectively. Complex <B>3</B> reacted with thallium(I) acetylacetonate [Tl(acac)], resulting in the formation of [{Ru(MeCHCN)(acac)(CO)(PPh<SUB>3</SUB>)}<SUB>2</SUB>] and [Ru(MeCHCN)(acac)(CO)(pic)(PPh<SUB>3</SUB>)]. 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.
