A chemical compound or mineral containing two phosphorus atoms or two phosphide units, often found in metal-phosphorus combinations.
From di- (two) + phosphide (phosphorus combined with a more electropositive element). Used in crystallography and mineralogy to describe natural and synthetic compounds.
Some diphosphides can act as semiconductors—materials that conduct electricity better when warm or when light hits them—making them potentially useful for electronics that currently use rare or expensive materials.
