The structure of the ordered form of the partially ordered cubic: α‐Ga 2 Se 3 is based on a tetragonal, body‐centred cell, with space group I 4 1 / acd , a = 23.235 (5), c = 10.828 (2) Å, Z = 48, D m = 4.91 g cm −3 at 30°C. Diffractometer data up to θ ~ 80° from Cu K α radiation are given for the β phase with nominal composition Ga 2 Se 3.03 .
