Materials Data on V2S5 by Materials Project
V2S5 crystallizes in the orthorhombic Pmmn space group. The structure is two-dimensional and consists of one V2S5 sheet oriented in the (0, 1, 0) direction. V5+ is bonded to five S2- atoms to form a mixture of distorted edge and corner-sharing VS5 trigonal bipyramids. There are a spread of V–S bond distances ranging from 2.02–2.42 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a single-bond geometry to one V5+ atom. In the second S2- site, S2- is bonded in a distorted bent 150 degrees geometry to two equivalent V5+ atoms. In the third S2- site, S2- is bonded in a distorted trigonal non-coplanar geometry to three equivalent V5+ atoms.
