The material described by VMn(Co2Si)2 is Tungsten-derived structured and crystallizes in the trigonal R-3m space group. V(1) is bonded in a distorted body-centered cubic geometry to two equivalent Co(1), six equivalent Co(2), and six equivalent Si(1) atoms. Mn(1) is bonded in a distorted body-centered cubic geometry to two equivalent Co(2), six equivalent Co(1), and six equivalent Si(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a distorted body-centered cubic geometry to one V(1), three equivalent Mn(1), and four equivalent Si(1) atoms. In the second Co site, Co(2) is bonded in a distorted body-centered cubic geometry to three equivalent V(1), one Mn(1), and four equivalent Si(1) atoms. Si(1) is bonded in a 14-coordinate geometry to three equivalent V(1), three equivalent Mn(1), four equivalent Co(1), and four equivalent Co(2) atoms. is represented by the CIF card [CIF]
