VCo2N3 is Enargite-like structured and crystallizes in the orthorhombic Cmc2_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 two equivalent V(1)N4 tetrahedra and corners with ten equivalent Co(1)N4 tetrahedra. Co(1) is bonded to one N(2) and three equivalent N(1) atoms to form CoN4 tetrahedra that share corners with five equivalent V(1)N4 tetrahedra and corners with seven equivalent Co(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent V(1) and two equivalent Co(1) atoms to form NV2Co2 tetrahedra that share corners with two equivalent N(2)V2Co2 tetrahedra and corners with ten equivalent N(1)VCo3 tetrahedra. In the second N site, N(1) is bonded to one V(1) and three equivalent Co(1) atoms to form NVCo3 tetrahedra that share corners with five equivalent N(2)V2Co2 tetrahedra and corners with seven equivalent N(1)VCo3 tetrahedra.

V(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form VN4 tetrahedra that share corners with two equivalent V(1)N4 tetrahedra and corners with ten equivalent Co(1)N4 tetrahedra. Both V(1)-N(1) bond lengths are 1.88 Å. There is one shorter (1.89 Å) and one longer (1.90 Å) V(1)-N(2) bond length. Co(1) is bonded to one N(2) and three equivalent N(1) atoms to form CoN4 tetrahedra that share corners with five equivalent V(1)N4 tetrahedra and corners with seven equivalent Co(1)N4 tetrahedra. The Co(1)-N(2) bond length is 1.87 Å. All Co(1)-N(1) bond lengths are 1.87 Å. There are two inequivalent N sites. In the first N site, N(2) is bonded to two equivalent V(1) and two equivalent Co(1) atoms to form NV2Co2 tetrahedra that share corners with two equivalent N(2)V2Co2 tetrahedra and corners with ten equivalent N(1)VCo3 tetrahedra.
