Cadmium (Ii) Phosphide

Cadmium (II) phosphide is a compound composed of the elements cadmium and phosphorus, with a chemical formula of Cd3P2. It is a crystalline solid that is insoluble in water but soluble in acids.

Cadmium (II) phosphide has a zincblende crystal structure, which consists of repeating units of two interpenetrating face-centered cubic lattices. In this structure, each cadmium ion is tetrahedrally coordinated to four phosphide ions, and each phosphide ion is tetrahedrally coordinated to four cadmium ions.

Cadmium (II) phosphide has a band gap energy of approximately 1.6 electron volts, which makes it a semiconductor material. It is commonly used in optoelectronic devices such as light-emitting diodes (LEDs) and solar cells, due to its ability to efficiently convert electrical energy into light.

In terms of its properties, cadmium (II) phosphide is a toxic substance that can pose health risks if ingested or inhaled. It is also considered hazardous waste and must be disposed of properly.
