CoGaN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Co(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CoN4 tetrahedra that share corners with four equivalent Co(1)N4 tetrahedra and corners with eight equivalent Ga(1)N4 tetrahedra. Ga(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GaN4 tetrahedra that share corners with four equivalent Ga(1)N4 tetrahedra and corners with eight equivalent Co(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Co(1) and two equivalent Ga(1) atoms to form corner-sharing NGa2Co2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Co(1) and two equivalent Ga(1) atoms to form corner-sharing NGa2Co2 tetrahedra.

Co(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form CoN4 tetrahedra that share corners with four equivalent Co(1)N4 tetrahedra and corners with eight equivalent Ga(1)N4 tetrahedra. There is one shorter (1.87 Å) and one longer (1.89 Å) Co(1)-N(1) bond length. There is one shorter (1.86 Å) and one longer (1.90 Å) Co(1)-N(2) bond length. Ga(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GaN4 tetrahedra that share corners with four equivalent Ga(1)N4 tetrahedra and corners with eight equivalent Co(1)N4 tetrahedra. There is one shorter (1.97 Å) and one longer (1.99 Å) Ga(1)-N(1) bond length. There is one shorter (1.95 Å) and one longer (1.97 Å) Ga(1)-N(2) bond length. There are two inequivalent N sites.
