The compound described by Y2Re3Si5 crystallizes in the tetragonal P4/mnc space group. Y(1) is bonded in a 11-coordinate geometry to two equivalent Re(1), two equivalent Re(2), two equivalent Si(2), three equivalent Si(3), and four equivalent Si(1) atoms. There are two inequivalent Re sites. In the first Re site, Re(1) is bonded in a 8-coordinate geometry to two equivalent Y(1), two equivalent Si(1), two equivalent Si(2), and two equivalent Si(3) atoms. In the second Re site, Re(2) is bonded to four equivalent Y(1), two equivalent Re(2), two equivalent Si(1), and four equivalent Si(3) atoms to form a mixture of face and corner-sharing ReY4Re2Si6 cuboctahedra. There are three inequivalent Si sites. In the first Si site, Si(3) is bonded in a 9-coordinate geometry to three equivalent Y(1), two equivalent Re(1), two equivalent Re(2), and two equivalent Si(1) atoms. In the second Si site, Si(1) is bonded in a 11-coordinate geometry to four equivalent Y(1), one Re(2), two equivalent Re(1), two equivalent Si(1), and two equivalent Si(3) atoms. In the third Si site, Si(2) is bonded in a 10-coordinate geometry to four equivalent Y(1), four equivalent Re(1), and two equivalent Si(2) atoms. is represented by the CIF file [CIF]
