Title: Materials Data on KCu2H2(SO5)2 by Materials Project

Abstract

KCu2H2(SO5)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. K1+ is bonded to eight O2- atoms to form distorted KO8 hexagonal bipyramids that share corners with four equivalent SO4 tetrahedra, edges with four equivalent CuO6 octahedra, and edges with two equivalent SO4 tetrahedra. There are six shorter (2.82 Å) and two longer (2.96 Å) K–O bond lengths. Cu+2.50+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent SO4 tetrahedra, edges with two equivalent KO8 hexagonal bipyramids, and edges with two equivalent CuO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.89–2.50 Å. H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent KO8 hexagonal bipyramids, corners with four equivalent CuO6 octahedra, and an edgeedge with one KO8 hexagonal bipyramid. The corner-sharing octahedra tilt angles range from 42–50°. There are a spread of S–O bond distances ranging from 1.46–1.52 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one K1+,more » two equivalent Cu+2.50+, and one S6+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one K1+, one Cu+2.50+, and one S6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two equivalent Cu+2.50+ and one H1+ atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one K1+ and one S6+ atom.« less
