The crystal structure described by V2(CrSi)3 crystallizes in the orthorhombic Ibam space group. V(1) is bonded in a 7-coordinate geometry to one Cr(1), two equivalent Si(1), and four equivalent Si(2) atoms. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded in a 7-coordinate geometry to one V(1), two equivalent Si(1), and four equivalent Si(2) atoms. In the second Cr site, Cr(2) is bonded in a 6-coordinate geometry to two equivalent Cr(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 four equivalent V(1), four equivalent Cr(1), and two equivalent Si(1) atoms. In the second Si site, Si(2) is bonded in a 10-coordinate geometry to four equivalent V(1), two equivalent Cr(2), and four equivalent Cr(1) atoms. is represented by the CIF file [CIF]
