The material described by BeSiN2 is Enargite-like structured and crystallizes in the trigonal P3m1 space group. Be(1) is bonded to one N(1) and three equivalent N(2) atoms to form BeN4 tetrahedra that share corners with six equivalent Be(1)N4 tetrahedra and corners with six equivalent Si(1)N4 tetrahedra. Si(1) is bonded to one N(2) and three equivalent N(1) atoms to form SiN4 tetrahedra that share corners with six equivalent Be(1)N4 tetrahedra and corners with six equivalent Si(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to one Be(1) and three equivalent Si(1) atoms to form NBeSi3 tetrahedra that share corners with six equivalent N(2)Be3Si tetrahedra and corners with six equivalent N(1)BeSi3 tetrahedra. In the second N site, N(2) is bonded to three equivalent Be(1) and one Si(1) atom to form NBe3Si tetrahedra that share corners with six equivalent N(2)Be3Si tetrahedra and corners with six equivalent N(1)BeSi3 tetrahedra. is represented by the CIF file [CIF]
