The crystal structure described by Mn10CuGe5 crystallizes in the tetragonal I422 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 4-coordinate geometry to four equivalent Ge(1) atoms. In the second Mn site, Mn(2) is bonded in a 6-coordinate geometry to one Cu(1), one Ge(2), and four equivalent Ge(1) atoms. Cu(1) is bonded in a distorted q6 geometry to eight equivalent Mn(2) and two equivalent Ge(2) atoms. There are two inequivalent Ge sites. In the first Ge site, Ge(1) is bonded in a 10-coordinate geometry to two equivalent Mn(1) and eight equivalent Mn(2) atoms. In the second Ge site, Ge(2) is bonded in a distorted q6 geometry to eight equivalent Mn(2) and two equivalent Cu(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
