pnictides
Pnictides are chemical compounds that contain one or more pnictogen elements, the group 15 elements nitrogen, phosphorus, arsenic, antimony, and bismuth. The term, derived from pnictogen, is used for a broad class of materials in which a pnictogen forms bonds with metals, metalloids, or nonmetals. In practice, pnictides encompass a wide range of compounds, with nitrogen-, phosphorus-, arsenic-, and antimony-containing examples being the most studied.
Common classes of pnictides include nitrides (N3−), phosphides (P3−), arsenides (As3−), antimonides (Sb3−), and bismuthides (Bi3−).
In condensed matter physics and materials science, iron pnictides (FeAs-based compounds) form a family of high-temperature
Synthesis and crystal chemistry of pnictides vary by class, but they are generally prepared by reactions between
