VCuN2 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 Cu(1)N4 tetrahedra. Cu(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CuN4 tetrahedra that share corners with four equivalent Cu(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 Cu(1) atoms to form corner-sharing NV2Cu2 tetrahedra. In the second N site, N(2) is bonded to two equivalent V(1) and two equivalent Cu(1) atoms to form corner-sharing NV2Cu2 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 Cu(1)N4 tetrahedra. There is one shorter (1.83 Å) and one longer (1.86 Å) V(1)-N(1) bond length. There is one shorter (1.84 Å) and one longer (1.85 Å) V(1)-N(2) bond length. Cu(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CuN4 tetrahedra that share corners with four equivalent Cu(1)N4 tetrahedra and corners with eight equivalent V(1)N4 tetrahedra. There is one shorter (2.04 Å) and one longer (2.05 Å) Cu(1)-N(1) bond length. There is one shorter (2.01 Å) and one longer (2.07 Å) Cu(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent V(1) and two equivalent Cu(1) atoms to form corner-sharing NV2Cu2 tetrahedra. In the second N site, N(2) is bonded to two equivalent V(1) and two equivalent Cu(1) atoms to form corner-sharing NV2Cu2 tetrahedra.
