The crystal structure described by Be3P2 crystallizes in the cubic Ia-3 space group. Be(1) is bonded to one P(2) and three equivalent P(1) atoms to form a mixture of corner and edge-sharing BeP4 tetrahedra. There are two inequivalent P sites. In the first P site, P(2) is bonded in a 6-coordinate geometry to six equivalent Be(1) atoms. In the second P site, P(1) is bonded in a 6-coordinate geometry to six equivalent Be(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
