The material structure described by CrMnSi2 crystallizes in the monoclinic P2_1 space group. Cr(1) is bonded in a 7-coordinate geometry to three equivalent Si(1) and four equivalent Si(2) atoms. Mn(1) is bonded in a 7-coordinate geometry to three equivalent Si(2) and four equivalent Si(1) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 7-coordinate geometry to three equivalent Cr(1) and four equivalent Mn(1) atoms. In the second Si site, Si(2) is bonded in a 7-coordinate geometry to four equivalent Cr(1) and three equivalent Mn(1) atoms. is represented by the CIF file [CIF]
