Materials Data on PSN(Cl2O)2 by Materials Project

Abstract

PNS(OCl2)2 is alpha-like structured and crystallizes in the orthorhombic Pbca space group. The structure is zero-dimensional and consists of eight PNS(OCl2)2 clusters. P5+ is bonded to one N5+ and three Cl1- atoms to form distorted PNCl3 tetrahedra that share a cornercorner with one SNClO2 tetrahedra. The P–N bond length is 1.57 Å. There is one shorter (1.97 Å) and two longer (2.00 Å) P–Cl bond length. N5+ is bonded in a distorted single-bond geometry to one P5+ and one S2- atom. The N–S bond length is 1.59 Å. S2- is bonded to one N5+, two O2-, and one Cl1- atom to form distorted SNClO2 tetrahedra that share a cornercorner with one PNCl3 tetrahedra. Both S–O bond lengths are 1.44 Å. The S–Cl bond length is 2.10 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S2- atom. There are four inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one P5+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one P5+ atom. In the third Cl1- site, Cl1- is bonded in a single-bond geometry to one S2- atom. In the fourth Cl1- site, Cl1- is bonded in a single-bond geometry to one P5+ atom.
