Palladium(II) and Platinum(II) Complexes with Arylthioethenes

Abstract

Di-, tri- and tetraarylthioethene derivatives prepared from di-,

tri- and tetrahaloethenes and the respective thiophenols

XC₆H₄SH(X = H or o-NH₂) have been isolated and reacted with

PdCl₂ and K₂PtCl₄ in different molar ratios to yeld mono- or dinuclear

Pd(II) and Pt(II) complexes of the general formula

[MLCl₂] and [M₂LCl₄]. respectively. The arylthioethene derivatives

together with their complexes have been characterized physicochemically

and spectroscopically. The X-ray single crystal structure

of the free ligand cis-1,2-bis-(o-aminophenylthio)ethene is described.
