Zinc arsenide can be prepared by the reaction of zinc with arsenic
3 Zn + 2 As → Zn3As2
Structureedit
Zn3As2 has a room-temperature tetragonal form that converts to a different tetragonal phase at 190 °C and to a third phase at 651 °C.[3] In the room-temperature form, the zinc atoms are tetrahedrally coordinated and the arsenic atoms are surrounded by six zinc atoms at the vertices of a distorted cube. The crystalline structure of zinc arsenide is very similar to that of cadmium arsenide (Cd3As2), zinc phosphide (Zn3P2) and cadmium phosphide (Cd3P2). These compounds of the Zn-Cd-P-As quaternary system exhibit full continuous solid-solution.[4]
Electronic structureedit
Its lowest direct and indirect bandgaps are within 30 meV of each other.[2]
