Anions [CuxSy]- reacted with P4 (g) to form products which were formally addition of P2 units, but are shown by density functional calculations and collisional induced dissociation to contain PnSm ligands co-ordinated to copper; the reactivities of the [CuxSy]- ions correlate with their geometrical rather than electronic structures, according to the principles which are described.
