The material structure described by Mn2Co2GeSi crystallizes in the orthorhombic Pmc2_1 space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 11-coordinate geometry to two equivalent Co(1), four equivalent Co(2), four equivalent Ge(1), and one Si(1) atom. In the second Mn site, Mn(2) is bonded in a 11-coordinate geometry to two equivalent Co(2), four equivalent Co(1), one Ge(1), and four equivalent Si(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 10-coordinate geometry to two equivalent Mn(1), four equivalent Mn(2), two equivalent Co(2), two equivalent Ge(1), and two equivalent Si(1) atoms. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to two equivalent Mn(2), four equivalent Mn(1), two equivalent Co(1), two equivalent Ge(1), and two equivalent Si(1) atoms. Ge(1) is bonded in a 9-coordinate geometry to one Mn(2), four equivalent Mn(1), two equivalent Co(1), and two equivalent Co(2) atoms. Si(1) is bonded in a 9-coordinate geometry to one Mn(1), four equivalent Mn(2), two equivalent Co(1), and two equivalent Co(2) atoms. is represented by the CIF file [CIF]
