摘要：

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