The compound described by YCo4Si crystallizes in the hexagonal P-6m2 space group. Y(1) is bonded in a 18-coordinate geometry to three equivalent Co(1), twelve equivalent Co(2), and three equivalent Si(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Co(2) atoms. In the second Co site, Co(2) is bonded to four equivalent Y(1), two equivalent Co(1), four equivalent Co(2), and two equivalent Si(1) atoms to form a mixture of edge, corner, and face-sharing CoY4Co6Si2 cuboctahedra. Si(1) is bonded in a 9-coordinate geometry to three equivalent Y(1) and six equivalent Co(2) atoms. is represented by the CIF card [CIF]
