Oligophosphanide anions

Up to now, metal phosphides have mainly been obtained either by solid-state synthetic techniques, under extreme conditions with long reaction times, or via the molecular phase to enable their use in the preparation of new materials. However, the renaissance and subsequent development of the chemistry of catenated oligophosphanide anions and their metal complexes may open up novel routes for the preparation of metal phosphides by thermal treatment of phosphorus-rich metal complexes.
