摘要: Abstract Reaction between 2,3,5,6-tetrakis(α-pyridyl)pyrazine (TPP) and the dimer [Pt2(PEt3)2Cl4] yielded an ionic complex of formula [{Pt(PEt3)Cl}2μ-(TPP)][Pt(PEt3)Cl3]2 (1), in which TPP behaves as a bis(bidentate) ligand two Pt atoms cation. Insertion SnCl2 into Pt–Cl bonds this compound led to unusual rearranged product, [{Pt(PEt3)Cl}2μ-(TPP)][Pt(SnCl3)4(PEt3)] (2), with rare example pentacoordinate Pt(II) species anionic moiety, where is at centre trigonal bipyramid, addition other square planar cationic moiety.
