The crystal structure described by Be3N2 crystallizes in the trigonal R3m space group. There are three inequivalent Be sites. In the first Be site, Be(1) is bonded in a distorted trigonal planar geometry to one N(2) and three equivalent N(1) atoms. In the second Be site, Be(2) is bonded to one N(1) and three equivalent N(2) atoms to form a mixture of distorted corner and edge-sharing BeN4 tetrahedra. In the third Be site, Be(3) is bonded to one N(1) and three equivalent N(2) atoms to form a mixture of corner and edge-sharing BeN4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Be(2), one Be(3), and three equivalent Be(1) atoms to form corner-sharing NBe5 trigonal bipyramids. In the second N site, N(2) is bonded in a 7-coordinate geometry to one Be(1), three equivalent Be(2), and three equivalent Be(3) atoms. is represented by the CIF file [CIF]
