The material structure described by W5Si3 crystallizes in the tetragonal I4/mcm space group. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 6-coordinate geometry to two equivalent Si(1) and four equivalent Si(2) atoms. In the second W site, W(2) is bonded in a 6-coordinate geometry to two equivalent W(2) and four equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to eight equivalent W(1) and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to two equivalent W(2) and eight equivalent W(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
