摘要: Abstract The reaction of nickel(II)chloride with γ-mercapto-propylamine in ethanolic solution gives the complex [Ni 3 (MPA) 4 ]Cl 2 (MPA=NH -(CH ) -S). complexes ]X (X=Br, I, ClO can be synthesized from chloride by addition sodium salt aqueous solution. crystal structure consists discrete divalent trinuclear cations and anions. Each sulphur atom ligand acts as a bridge between two nickel atoms, nitrogen atoms complete coordination around terminal atoms. geometry metal is square-planar. electronic IR spectra indicate that all these compounds are composed ] 2+ X − ions.
