MnGeN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MnN4 tetrahedra that share corners with four equivalent Mn(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 Mn(1)N4 tetrahedra. There are two inequivalent N sites. In the first N site, N(1) is bonded to two equivalent Mn(1) and two equivalent Ge(1) atoms to form corner-sharing NMn2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mn(1) and two equivalent Ge(1) atoms to form corner-sharing NMn2Ge2 tetrahedra.
MnGeN2 is Enargite-like structured and crystallizes in the orthorhombic Pna2_1 space group. Mn(1) is bonded to two equivalent N(1) and two equivalent N(2) atoms to form MnN4 tetrahedra that share corners with four equivalent Mn(1)N4 tetrahedra and corners with eight equivalent Ge(1)N4 tetrahedra. Both Mn(1)-N(1) bond lengths are 2.14 Å. There is one shorter (2.12 Å) and one longer (2.13 Å) Mn(1)-N(2) bond length. 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 Mn(1)N4 tetrahedra. There is one shorter (1.89 Å) and one longer (1.90 Å) Ge(1)-N(1) bond length. There is one shorter (1.88 Å) and one longer (1.89 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 Mn(1) and two equivalent Ge(1) atoms to form corner-sharing NMn2Ge2 tetrahedra. In the second N site, N(2) is bonded to two equivalent Mn(1) and two equivalent Ge(1) atoms to form corner-sharing NMn2Ge2 tetrahedra.
