Materials Data on Cu2(SO4)3 by Materials Project

Abstract

Cu2(SO4)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Cu3+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with five SO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.89–2.30 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with three equivalent CuO5 trigonal bipyramids. There are a spread of S–O bond distances ranging from 1.43–1.52 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with four equivalent CuO5 trigonal bipyramids. There is two shorter (1.46 Å) and two longer (1.52 Å) S–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one Cu3+ and one S6+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu3+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu3+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Cu3+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cu3+ and one S6+ atom.
