The structure described by Dy2Re3Si5 crystallizes in the tetragonal P4/mnc space group. Dy(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 Dy(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 Dy(1), two equivalent Re(2), two equivalent Si(1), and four equivalent Si(3) atoms to form a mixture of face and corner-sharing ReDy4Re2Si6 cuboctahedra. There are three inequivalent Si sites. In the first Si site, Si(3) is bonded in a 9-coordinate geometry to three equivalent Dy(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 Dy(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 Dy(1), four equivalent Re(1), and two equivalent Si(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
