Materials Data on P4Se3 by Materials Project
P4Se3 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of sixteen tetraphosphorous triselenide molecules. there are two inequivalent P+1.50+ sites. In the first P+1.50+ site, P+1.50+ is bonded in a single-bond geometry to one Se2- atom. The P–Se bond length is 2.26 Å. In the second P+1.50+ site, P+1.50+ is bonded in a distorted trigonal non-coplanar geometry to three Se2- atoms. There are two shorter (2.27 Å) and one longer (2.28 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 P+1.50+ atoms. The Se–P bond length is 2.26 Å. In the second Se2- site, Se2- is bonded in a water-like geometry to two P+1.50+ atoms.

Materials Data on Cu3P8(Se2I)3 by Materials Project
(CuI)3(P4Se3)2 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of four iodocopper molecules; eight tetraphosphorous triselenide molecules; and two CuI ribbons oriented in the (1, 0, 0) direction. In each CuI ribbon, Cu+1.67+ is bonded in a distorted water-like geometry to two equivalent I1- atoms. There are one shorter (2.64 Å) and one longer (2.74 Å) Cu–I bond lengths. I1- is bonded in a bent 120 degrees geometry to two equivalent Cu+1.67+ atoms.

Materials Data on Cu3P8(Se2Br)3 by Materials Project
(CuBr)3(P4Se3)2 crystallizes in the orthorhombic Pnma space group. The structure is one-dimensional and consists of eight tetraphosphorous triselenide molecules and six CuBr ribbons oriented in the (1, 0, 0) direction. In each CuBr ribbon, Cu+1.67+ is bonded in a water-like geometry to two equivalent Br1- atoms. There are one shorter (2.47 Å) and one longer (2.50 Å) Cu–Br bond lengths. Br1- is bonded in a bent 120 degrees geometry to two equivalent Cu+1.67+ atoms.
