MgGeN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Ge(1)N4 tetrahedra. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GeN4 tetrahedra that share corners with four equivalent Ge(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Ge(1) atoms to form corner-sharing NMg2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Ge(1) atoms to form corner-sharing NMg2Ge2 tetrahedra.
MgGeN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mg(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MgN4 tetrahedra that share corners with four equivalent Mg(1)N4 tetrahedra and corners with eight equivalent Ge(1)N4 tetrahedra. There is one shorter (2.10 Å) and one longer (2.11 Å) Mg(1)-N(1) bond length. Both Mg(1)-N(2) bond lengths are 2.07 Å. Ge(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form GeN4 tetrahedra that share corners with four equivalent Ge(1)N4 tetrahedra and corners with eight equivalent Mg(1)N4 tetrahedra. Both Ge(1)-N(1) bond lengths are 1.87 Å. There is one shorter (1.85 Å) and one longer (1.87 Å) Ge(1)-N(2) bond length. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mg(1) and two equivalent Ge(1) atoms to form corner-sharing NMg2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mg(1) and two equivalent Ge(1) atoms to form corner-sharing NMg2Ge2 tetrahedra.
