The structure described by Mn2CoGe crystallizes in the cubic F-43m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded to four equivalent Mn(2) and four equivalent Ge(1) atoms to form distorted edge-sharing MnMn4Ge4 tetrahedra. In the second Mn site, Mn(2) is bonded in a 14-coordinate geometry to four equivalent Mn(1), four equivalent Co(1), and six equivalent Ge(1) atoms. Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mn(2) and four equivalent Ge(1) atoms. Ge(1) is bonded in a distorted body-centered cubic geometry to four equivalent Mn(1), six equivalent Mn(2), and four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
