VFeSe3FeSe crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one iron selenide molecule and one VFeSe3 cluster. In the VFeSe3 cluster, V(1) is bonded in a 1-coordinate geometry to one Se(3) and one Se(4) atom. Fe(2) is bonded in a 2-coordinate geometry to one Se(1) and one Se(4) atom. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a 1-coordinate geometry to one Fe(2) atom. In the second Se site, Se(3) is bonded in a single-bond geometry to one V(1) atom. In the third Se site, Se(4) is bonded in a distorted water-like geometry to one V(1) and one Fe(2) atom.
