WReSi4 crystallizes in the tetragonal P4/mmm space group. W(1) is bonded in a distorted q6 geometry to two equivalent Si(1) and eight equivalent Si(2) atoms. Re(1) is bonded in a distorted q6 geometry to two equivalent Si(2) and eight equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 10-coordinate geometry to one W(1), four equivalent Re(1), one Si(1), and four equivalent Si(2) atoms. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to four equivalent W(1), one Re(1), one Si(2), and four equivalent Si(1) atoms.
