Mn2NiSn is Zintl Phase-derived structured and crystallizes in the cubic F-43m space group. There are two inequivalent Mn sites. In the first Mn site, Mn(1) is bonded in a 14-coordinate geometry to four equivalent Mn(2), four equivalent Ni(1), and six equivalent Sn(1) atoms. In the second Mn site, Mn(2) is bonded to four equivalent Mn(1), six equivalent Ni(1), and four equivalent Sn(1) atoms to form a mixture of distorted face and corner-sharing MnMn4Ni6Sn4 tetrahedra. Ni(1) is bonded in a 14-coordinate geometry to four equivalent Mn(1), six equivalent Mn(2), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 14-coordinate geometry to four equivalent Mn(2), six equivalent Mn(1), and four equivalent Ni(1) atoms.
