Phosphidogermanate

Phosphidogermanates are chemical compounds that have phosphorus bound to germanium to yield anions. They are in the category of phosphidotetrelates and also pnictides. They are analogous to nitridogermanates, phosphidoaluminates, phosphidogallates, phosphidoindates, phosphidosilicates or phosphidostannates.

They are under investigation as infrared non-linear optic materials and solid-state electrolytes.
