Materials Data on P4Se3Br2 by Materials Project
P4Se3Br2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight P4Se3Br2 clusters. there are two inequivalent P2+ sites. In the first P2+ site, P2+ is bonded in a water-like geometry to one Se2- and one Br1- atom. The P–Se bond length is 2.30 Å. The P–Br bond length is 2.29 Å. In the second P2+ site, P2+ is bonded in a water-like geometry to two Se2- atoms. There are one shorter (2.26 Å) and one longer (2.29 Å) P–Se bond lengths. There are two inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a water-like geometry to two P2+ atoms. In the second Se2- site, Se2- is bonded in a distorted water-like geometry to two equivalent P2+ atoms. Br1- is bonded in a single-bond geometry to one P2+ atom.
