Phosphide minerals

Natural examples (is a common mineral in some meteorites).

• Allabogdanite

• Schreibersite

In chemistry, a phosphide is a compound containing the P^3- ion or its equivalent. Most commonly encountered on the binary phosphides, i.e. those materials consisting only of phosphorus and a less electronegative element. Numerous are polyphosphides, which are solids consisting of anionic chains or clusters of phosphorus. Phosphides are known with the majority of less electronegative elements with the exception of Hg, Pb, Sb, Bi, Te, and Po.
