The crystal structure described by U2Os3Si5 crystallizes in the monoclinic C2/c space group. U(1) is bonded in a 16-coordinate geometry to two equivalent Os(2), four equivalent Os(1), two equivalent Si(2), two equivalent Si(3), two equivalent Si(4), and four equivalent Si(1) atoms. There are two inequivalent Os sites. In the first Os site, Os(2) is bonded in a 6-coordinate geometry to four equivalent U(1), one Si(2), one Si(4), and four equivalent Si(1) atoms. In the second Os site, Os(1) is bonded in a 5-coordinate geometry to four equivalent U(1), one Si(1), one Si(2), one Si(4), and two equivalent Si(3) atoms. There are four inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to four equivalent U(1), one Os(1), two equivalent Os(2), one Si(2), and one Si(4) atom. In the second Si site, Si(2) is bonded in a 3-coordinate geometry to four equivalent U(1), one Os(2), two equivalent Os(1), and two equivalent Si(1) atoms. In the third Si site, Si(3) is bonded in a 6-coordinate geometry to four equivalent U(1) and four equivalent Os(1) atoms. In the fourth Si site, Si(4) is bonded in a 9-coordinate geometry to four equivalent U(1), one Os(2), two equivalent Os(1), and two equivalent Si(1) atoms. is represented by the CIF card [CIF]
