A hydridoruthenium(II) complex reacted easily with acrylonitrile and fumaronitrile to give chloro-bridged binuclear (1-cyanoethyl)ruthenium(II) complexes, <2> (2) and <2>, respectively.Complex 2 reacted with 4-picoline (pic), Na (Pz=1-pyrazolyl), Na, and Na*3H2O to afford the corresponding (1-cyanoethyl)ruthenium(II) complexes, <2> (3), (accompanied by a small amount of ), , and Na, respectively.Complex 3 reacted with thallium(I) acetylacetonate , resulting in the formation of <2> and .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.
