Materials Data on NaCuCSO7 by Materials Project
NaCuCSO7 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to seven O2- atoms. There are a spread of Na–O bond distances ranging from 2.33–3.04 Å. Cu3+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent SO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.91–2.47 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.23–1.33 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent CuO6 octahedra. The corner-sharing octahedra tilt angles range from 37–46°. There are a spread of S–O bond distances ranging from 1.45–1.54 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Na1+ and one C4+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Na1+, one Cu3+, and one C4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Cu3+, and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cu3+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Cu3+, and one S6+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Cu3+, and one S6+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to one Na1+, one Cu3+, and one S6+ atom.
