The material structure described by Mn2Ni2GeSi 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 Ni(1), four equivalent Ni(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 Ni(2), four equivalent Ni(1), one Ge(1), and four equivalent Si(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 12-coordinate geometry to two equivalent Mn(1), four equivalent Mn(2), two equivalent Ni(2), two equivalent Ge(1), and two equivalent Si(1) atoms. In the second Ni site, Ni(2) is bonded to two equivalent Mn(2), four equivalent Mn(1), two equivalent Ni(1), two equivalent Ge(1), and two equivalent Si(1) atoms to form a mixture of distorted face and corner-sharing NiMn6Si2Ni2Ge2 cuboctahedra. Ge(1) is bonded in a 9-coordinate geometry to one Mn(2), four equivalent Mn(1), two equivalent Ni(1), and two equivalent Ni(2) atoms. Si(1) is bonded in a 9-coordinate geometry to one Mn(1), four equivalent Mn(2), two equivalent Ni(1), and two equivalent Ni(2) atoms. is represented by the CIF card [CIF]
