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]
