NAlVN is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. V(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form VN4 tetrahedra that share corners with four equivalent V(1)N4 tetrahedra and corners with eight equivalent Al(1)N4 tetrahedra. Al(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form AlN4 tetrahedra that share corners with four equivalent Al(1)N4 tetrahedra and corners with eight equivalent V(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent V(1) and two equivalent Al(1) atoms to form corner-sharing NAl2V2 tetrahedra. In the second N site, N(2) is bonded to two equivalent V(1) and two equivalent Al(1) atoms to form corner-sharing NAl2V2 tetrahedra.

V(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form VN4 tetrahedra that share corners with four equivalent V(1)N4 tetrahedra and corners with eight equivalent Al(1)N4 tetrahedra. There is one shorter (1.97 Å) and one longer (1.98 Å) V(1)-N(1) bond length. There is one shorter (1.99 Å) and one longer (2.01 Å) V(1)-N(2) bond length. Al(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form AlN4 tetrahedra that share corners with four equivalent Al(1)N4 tetrahedra and corners with eight equivalent V(1)N4 tetrahedra. There is one shorter (1.90 Å) and one longer (1.92 Å) Al(1)-N(1) bond length. Both Al(1)-N(2) bond lengths are 1.90 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent V(1) and two equivalent Al(1) atoms to form corner-sharing NAl2V2 tetrahedra. In the second N site, N(2) is bonded to two equivalent V(1) and two equivalent Al(1) atoms to form corner-sharing NAl2V2 tetrahedra.
