Reaction of the anion [WCl4(CBut)]– with tetrasulphur tetranitride. Formation and crystal structure of [AsPh4][WCl3O(OS2N2)]

Abstract

The reaction of [AsPh₄][WCl₄(CBu^t)] with S₄N₄ in dichloromethane leads to [AsPh₄][WCl₄(S₂N₃)], and, if traces of water are present, to the salt [AsPh₄][WCl₃O(OS₂N₂)]. The latter has been characterized by i.r. and u.v.-visible spectroscopy and by X-ray crystallography. It crystallizes in the triclinic space group P with a= 8.077(1), b= 12.675(2), c= 13.480(2)Å, α= 88.49(1), β= 82.13(1), γ= 87.98(1)°, and Z= 2.
