Title: Materials Data on NaCr(SO4)2 by Materials Project

Abstract

NaCr(SO4)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Na1+ is bonded in a distorted hexagonal planar geometry to six O2- atoms. There are two shorter (2.59 Å) and four longer (2.66 Å) Na–O bond lengths. Cr3+ is bonded to six O2- atoms to form CrO6 octahedra that share corners with six equivalent SO4 tetrahedra. There are two shorter (1.99 Å) and four longer (2.02 Å) Cr–O bond lengths. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three equivalent CrO6 octahedra. The corner-sharing octahedra tilt angles range from 39–46°. There are a spread of S–O bond distances ranging from 1.45–1.51 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one Na1+ and one S6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Cr3+, and one S6+ atom. In the third O2- site, O2- is bonded in a bent 150 degrees geometry to one Cr3+ and one S6+ atom.
