The material described by VMn(Ni2Sn)2 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. V(1) is bonded in a distorted body-centered cubic geometry to two equivalent Ni(1); six Ni(2,2); and six equivalent Sn(1) atoms. Mn(1) is bonded in a distorted body-centered cubic geometry to two Ni(2,2); six equivalent Ni(1); and six equivalent Sn(1) atoms. There are four inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a distorted body-centered cubic geometry to one V(1), three equivalent Mn(1), and four equivalent Sn(1) atoms. In the second Ni site, Ni(2) is bonded in a distorted body-centered cubic geometry to three equivalent V(1), one Mn(1), and four equivalent Sn(1) atoms. In the third Ni site, Ni(2) is bonded in a distorted body-centered cubic geometry to three equivalent V(1), one Mn(1), and four equivalent Sn(1) atoms. In the fourth Ni site, Ni(2) is bonded in a distorted body-centered cubic geometry to three equivalent V(1), one Mn(1), and four equivalent Sn(1) atoms. Sn(1) is bonded in a 14-coordinate geometry to three equivalent V(1); three equivalent Mn(1); four equivalent Ni(1); and four Ni(2,2) atoms. is represented by the CIF file [CIF]
