The material structure described by Ce10(NiSn)3 crystallizes in the orthorhombic Fmm2 space group. There are four inequivalent Ce sites. In the first Ce site, Ce(1) is bonded in a 5-coordinate geometry to one Ni(1), one Ni(2), one Sn(1), and two equivalent Sn(2) atoms. In the second Ce site, Ce(2) is bonded in a 4-coordinate geometry to two equivalent Ce(4), one Ni(2), two equivalent Ni(1), and two equivalent Sn(2) atoms. In the third Ce site, Ce(3) is bonded to two equivalent Ni(1), one Sn(1), and two equivalent Sn(2) atoms to form a mixture of distorted face and corner-sharing CeNi2Sn3 trigonal bipyramids. In the fourth Ce site, Ce(4) is bonded in a 8-coordinate geometry to two equivalent Ce(2), one Ni(2), two equivalent Ni(1), one Sn(1), and two equivalent Sn(2) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 9-coordinate geometry to two equivalent Ce(1), two equivalent Ce(2), two equivalent Ce(3), two equivalent Ce(4), and one Ni(1) atom. In the second Ni site, Ni(2) is bonded in a 9-coordinate geometry to two equivalent Ce(2), two equivalent Ce(4), four equivalent Ce(1), and one Sn(1) atom. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 9-coordinate geometry to two equivalent Ce(3), two equivalent Ce(4), four equivalent Ce(1), and one Ni(2) atom. In the second Sn site, Sn(2) is bonded in a distorted q6 geometry to two equivalent Ce(2), two equivalent Ce(3), two equivalent Ce(4), and four equivalent Ce(1) atoms. is represented by the CIF file [CIF]
