The crystal structure described by V(FeSe2)2 crystallizes in the monoclinic C2/m space group. V(1) is bonded to two equivalent Se(2) and four equivalent Se(1) atoms to form edge-sharing VSe6 octahedra. Fe(1) is bonded in a 6-coordinate geometry to three equivalent Se(1) and three equivalent Se(2) atoms. There are two inequivalent Se sites. In the first Se site, Se(2) is bonded in a 4-coordinate geometry to one V(1) and three equivalent Fe(1) atoms. In the second Se site, Se(1) is bonded in a 5-coordinate geometry to two equivalent V(1) and three equivalent Fe(1) atoms. is represented by the CIF file [CIF]
