FeGaN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Fe(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form FeN4 tetrahedra that share corners with four equivalent Fe(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 Fe(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Fe(1) and two equivalent Ga(1) atoms to form corner-sharing NGa2Fe2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Fe(1) and two equivalent Ga(1) atoms to form corner-sharing NGa2Fe2 tetrahedra.
FeGaN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Fe(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form FeN4 tetrahedra that share corners with four equivalent Fe(1)N4 tetrahedra and corners with eight equivalent Ga(1)N4 tetrahedra. Both Fe(1)-N(1) bond lengths are 1.87 Å. There is one shorter (1.86 Å) and one longer (1.88 Å) Fe(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 Fe(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. In the first N site, N(1) is bonded to two equivalent Fe(1) and two equivalent Ga(1) atoms to form corner-sharing NGa2Fe2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Fe(1) and two equivalent Ga(1) atoms to form corner-sharing NGa2Fe2 tetrahedra.
