The preparation and X-ray structure of Pt(Se3N)Cl(PMe2Ph)

Reaction of Se4N4 with [PtCl2(PMe2Ph)]2, in refluxing CHCl3, results in Pt(Se3N)Cl(PMe2Ph), (1), the first example of a metal selenium–nitrogen complex, which contains the bidentate, selenium-bound Se3N– ligand; from X-ray crystallography (1) is square planar with a bidentate Se3N– ligand co-ordinated through two selenium atoms.
