The material structure described by Y3(Co2Sn)4 is Hexagonal Laves-derived structured and crystallizes in the hexagonal P6_3mc space group. Y(1) is bonded in a 14-coordinate geometry to two equivalent Co(1), two equivalent Co(3), four equivalent Co(4), two equivalent Sn(2), and four equivalent Sn(1) atoms. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent Y(1), two equivalent Co(1), two equivalent Co(2), three equivalent Co(4), and three equivalent Sn(1) atoms to form distorted CoY2Co7Sn3 cuboctahedra that share corners with four equivalent Co(1)Y2Co7Sn3 cuboctahedra, faces with two equivalent Co(2)Co9Sn3 cuboctahedra, and faces with six equivalent Co(1)Y2Co7Sn3 cuboctahedra. In the second Co site, Co(2) is bonded to three equivalent Co(4), six equivalent Co(1), and three equivalent Sn(1) atoms to form CoCo9Sn3 cuboctahedra that share faces with two equivalent Co(2)Co9Sn3 cuboctahedra and faces with six equivalent Co(1)Y2Co7Sn3 cuboctahedra. In the third Co site, Co(3) is bonded in a 10-coordinate geometry to six equivalent Y(1), one Sn(2), and three equivalent Sn(1) atoms. In the fourth Co site, Co(4) is bonded in a 12-coordinate geometry to four equivalent Y(1), one Co(2), three equivalent Co(1), one Sn(2), and three equivalent Sn(1) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 12-coordinate geometry to four equivalent Y(1), one Co(2), one Co(3), three equivalent Co(1), and three equivalent Co(4) atoms. In the second Sn site, Sn(2) is bonded in a 10-coordinate geometry to six equivalent Y(1), one Co(3), and three equivalent Co(4) atoms. is represented by the CIF card [CIF]
