The compound described by YNi3Sn2 crystallizes in the hexagonal P-62m space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 18-coordinate geometry to three equivalent Ni(2), six equivalent Ni(1), three equivalent Sn(1), and six equivalent Sn(2) atoms. In the second Y site, Y(2) is bonded in a 12-coordinate geometry to six equivalent Ni(1), six equivalent Ni(2), and six equivalent Sn(1) atoms. There are two inequivalent Ni sites. In the first Ni site, Ni(1) is bonded in a 10-coordinate geometry to one Y(2), two equivalent Y(1), one Ni(1), two equivalent Ni(2), two equivalent Sn(1), and two equivalent Sn(2) atoms. In the second Ni site, Ni(2) is bonded in a 12-coordinate geometry to two equivalent Y(1), two equivalent Y(2), four equivalent Ni(1), two equivalent Sn(1), and two equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to two equivalent Y(1), two equivalent Y(2), two equivalent Ni(2), and four equivalent Ni(1) atoms. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to four equivalent Y(1), two equivalent Ni(2), and four equivalent Ni(1) atoms. is represented by the CIF card [CIF]
