Unusual reactivity of a luminescent bis-µ-sulfido platinum(II) dimer with methylene chloride. X-Ray structural characterization of [Pt2(µ-S)2(dppy)4] and [Pt(dppy)2(S2CH2)](dppy = 2-diphenylphosphinopyridine)

Abstract

Reaction of [Pt(dppy)₂Cl₂] with NaSH in the presence of triethylamine in MeCN produces a luminescent dimeric [Pt₂(µ-S)₂(dppy)₄] complex 1 which is characterized by X-ray crystallography; its unusual reactivity with CH₂Cl₂ to give novel monomeric [Pt(dppy)₂(S₂CH₂)]2, identified by both NMR spectroscopy and X-ray crystallography, is described (dppy = 2-diphenylphosphinopyridine).
