The compound described by BeGeN2 is Chalcopyrite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Be(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form BeN4 tetrahedra that share corners with four equivalent Be(1)N4 tetrahedra and corners with eight equivalent Ge(1)N4 tetrahedra. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GeN4 tetrahedra that share corners with four equivalent Ge(1)N4 tetrahedra and corners with eight equivalent Be(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Be(1) and two equivalent Ge(1) atoms to form corner-sharing NBe2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Be(1) and two equivalent Ge(1) atoms to form corner-sharing NBe2Ge2 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
