The structure described by Cu2MnGeS4 is Stannite-like structured and crystallizes in the orthorhombic Pmn2_1 space group. Mn(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form MnS4 tetrahedra that share corners with four equivalent Ge(1)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. Cu(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form CuS4 tetrahedra that share corners with four equivalent Mn(1)S4 tetrahedra, corners with four equivalent Cu(1)S4 tetrahedra, and corners with four equivalent Ge(1)S4 tetrahedra. Ge(1) is bonded to one S(2), one S(3), and two equivalent S(1) atoms to form GeS4 tetrahedra that share corners with four equivalent Mn(1)S4 tetrahedra and corners with eight equivalent Cu(1)S4 tetrahedra. There are three inequivalent S sites. In the first S site, S(1) is bonded to one Mn(1), two equivalent Cu(1), and one Ge(1) atom to form corner-sharing SMnCu2Ge tetrahedra. In the second S site, S(2) is bonded to one Mn(1), two equivalent Cu(1), and one Ge(1) atom to form corner-sharing SMnCu2Ge tetrahedra. In the third S site, S(3) is bonded to one Mn(1), two equivalent Cu(1), and one Ge(1) atom to form corner-sharing SMnCu2Ge tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
