The material structure described by W2Mo3Si3 crystallizes in the orthorhombic Ibam space group. W(1) is bonded in a 7-coordinate geometry to one Mo(1), two equivalent Mo(2), two equivalent Si(1), and four equivalent Si(2) atoms. There are two inequivalent Mo sites. In the first Mo site, Mo(1) is bonded in a 7-coordinate geometry to one W(1), two equivalent Mo(2), two equivalent Si(1), and four equivalent Si(2) atoms. In the second Mo site, Mo(2) is bonded in a 14-coordinate geometry to four equivalent W(1), two equivalent Mo(2), four equivalent Mo(1), 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 four equivalent W(1), four equivalent Mo(1), and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to four equivalent W(1), two equivalent Mo(2), and four equivalent Mo(1) atoms. is represented by the CIF file [CIF]
