The material structure described by Y2Co3Si5 is delta Molybdenum Boride-derived structured and crystallizes in the monoclinic C2/c space group. Y(1) is bonded in a 17-coordinate geometry to two equivalent Co(2), five equivalent Co(1), two equivalent Si(2), two equivalent Si(3), two equivalent Si(4), and four 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 five equivalent Y(1), one Si(1), one Si(2), one Si(4), and two equivalent Si(3) atoms. In the second Co site, Co(2) is bonded in a 12-coordinate geometry to four equivalent Y(1), two equivalent Co(2), one Si(2), one Si(4), and four equivalent Si(1) atoms. There are four inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to four equivalent Y(1), one Co(1), two equivalent Co(2), one Si(2), and one Si(4) atom. In the second Si site, Si(2) is bonded in a 11-coordinate geometry to four equivalent Y(1), one Co(2), two equivalent Co(1), two equivalent Si(1), and two equivalent Si(4) atoms. In the third Si site, Si(3) is bonded in a 6-coordinate geometry to four equivalent Y(1) and four equivalent Co(1) atoms. In the fourth Si site, Si(4) is bonded in a 11-coordinate geometry to four equivalent Y(1), one Co(2), two equivalent Co(1), two equivalent Si(1), and two equivalent Si(2) atoms. is represented by the CIF file [CIF]
