Reaction of sulfur-containing structural units of transition metals

Two tri-n-butylphosphme-participated ( PBu3n) nickel (Ⅱ) complexes of 2-mercaptophenol(H2mp),i.e,Ni2Ru(mp)3(Hmp)(PBu3n)3 3 exhibiting a curved heterotrinuclear metal skeleton and its mononuclear "synthon",[HNEt3] [Ni(mp) (Hmp) (PBu3n)] 1 were synthesized and characterized by X-crystallography and 1H NMR,FAB-MS and cyclic valtammogram measurements.The nickel(Ⅱ) center in 1 has a square-planar geometry For 3,the ruthenium(Ⅲ) atom is in a distorted octahedral environment and the two mckel(Ⅱ) atoms exhibit square-planar and rare triangle-planar geometries,respectively.The Ni (1)-Ru-Ni(2 ) arrangement is severely asymmetric with the distances 0.254 and 0.394 nm,respectively,for Ni(1)-Ru and Ni(2)-Ru.The structural regularities of relevant complexes are summarized in relation to the structural as well as spectra data.
