The material structure described by VFe3Si4 crystallizes in the trigonal R3 space group. V(1) is bonded in a 13-coordinate geometry to six equivalent Fe(1), one Si(1), and six equivalent Si(2) atoms. Fe(1) is bonded in a 9-coordinate geometry to two equivalent V(1), two equivalent Si(1), and five equivalent Si(2) atoms. There are two inequivalent Si sites. In the first Si site, Si(1) is bonded in a 7-coordinate geometry to one V(1) and six equivalent Fe(1) atoms. In the second Si site, Si(2) is bonded in a 7-coordinate geometry to two equivalent V(1) and five equivalent Fe(1) atoms. is represented by the CIF card [CIF]
