Ytterbium(III) phosphide is an inorganic compound of ytterbium and phosphorus with the chemical formula YbP.[1] This is one of the phosphides of ytterbium.[2][3]
Synthesis
Ytterbium and phosphine reacts in
liquid ammonia to form Yb(PH2)2·5NH3, which can be decomposed to obtain ytterbium(III) phosphide:[4]
- Yb(PH2)2•5NH3 → Yb(PH2)2 + 5NH3
- 2Yb(PH2)2 → YbP + 2PH3 + H2
Physical properties
Ytterbium(III) phosphide decomposes at or above 550 °C:
- 12 YbP → 4 Yb3P2 + P4
It is soluble in hydrochloric acid, nitric acid, and aqua regia.
The compound forms black crystals of a
cubic system, space group Fm3m.[5]
Uses
The ytterbium(III) phosphide compound is a semiconductor used in high power, high frequency applications and in laser and other photo diodes.[1]
