Abstract

PS1 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four tetraphosphorous tetrasulfide molecules. there are two inequivalent P2- sites. In the first P2- site, P2- is bonded in a distorted L-shaped geometry to one P2- and two S2+ atoms. The P–P bond length is 2.39 Å. Both P–S bond lengths are 2.12 Å. In the second P2- site, P2- is bonded in a distorted L-shaped geometry to one P2- and two S2+ atoms. Both P–S bond lengths are 2.12 Å. There are three inequivalent S2+ sites. In the first S2+ site, S2+ is bonded in a water-like geometry to two equivalent P2- atoms. In the second S2+ site, S2+ is bonded in a water-like geometry to two equivalent P2- atoms. In the third S2+ site, S2+ is bonded in a water-like geometry to two P2- atoms.
