Materials Data on CuHS(NO)4 by Materials Project

Abstract

CuHS(NO)4 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of four CuHS(NO)4 clusters. Cu1+ is bonded in a distorted bent 150 degrees geometry to two equivalent N2+, one H1+, and one O2- atom. Both Cu–N bond lengths are 1.95 Å. The Cu–H bond length is 1.51 Å. The Cu–O bond length is 1.84 Å. There are two inequivalent N2+ sites. In the first N2+ site, N2+ is bonded in a single-bond geometry to one N2+ atom. The N–N bond length is 1.11 Å. In the second N2+ site, N2+ is bonded in a distorted linear geometry to one Cu1+ and one N2+ atom. H1+ is bonded in a single-bond geometry to one Cu1+ atom. S2- is bonded in a tetrahedral geometry to four O2- atoms. There is three shorter (1.47 Å) and one longer (1.56 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Cu1+ and one S2- atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S2- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one S2- atom.
