The material structure described by Re2Si crystallizes in the monoclinic P2_1/c space group. There are four inequivalent Re sites. In the first Re site, Re(1) is bonded in a 11-coordinate geometry to one Re(1), two equivalent Re(3), two equivalent Re(4), three equivalent Re(2), one Si(1), and two equivalent Si(2) atoms. In the second Re site, Re(2) is bonded in a 10-coordinate geometry to one Re(3), two equivalent Re(4), three equivalent Re(1), two equivalent Si(1), and two equivalent Si(2) atoms. In the third Re site, Re(3) is bonded in a 11-coordinate geometry to one Re(2), one Re(3), two equivalent Re(1), two equivalent Re(4), two equivalent Si(2), and three equivalent Si(1) atoms. In the fourth Re site, Re(4) is bonded in a 10-coordinate geometry to two equivalent Re(1), two equivalent Re(2), two equivalent Re(3), two equivalent Si(1), and two equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 9-coordinate geometry to one Re(1), two equivalent Re(2), two equivalent Re(4), three equivalent Re(3), and one Si(2) atom. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to two equivalent Re(1), two equivalent Re(2), two equivalent Re(3), two equivalent Re(4), one Si(1), and one Si(2) atom. is represented by the CIF file [CIF]
