Abstract

Cu(H3O)2CuH14(SO8)2 crystallizes in the triclinic P-1 space group. The structure is one-dimensional and consists of one Cu(H3O)2 cluster and one CuH14(SO8)2 ribbon oriented in the (1, 0, 0) direction. In the Cu(H3O)2 cluster, Cu2+ is bonded in a distorted linear geometry to two equivalent H1+ and two equivalent O2- atoms. Both Cu–H bond lengths are 2.21 Å. Both Cu–O bond lengths are 1.80 Å. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one H1+ atom. The H–H bond length is 0.75 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the third H1+ site, H1+ is bonded in a linear geometry to one Cu2+ and one H1+ atom. O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one H1+ atom. In the CuH14(SO8)2 ribbon, Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with two equivalent SO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.91–2.61 Å. There are seven inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the second H1+ site, H1+ is bonded in a distorted linear geometry to two O2- atoms. There is one shorter (1.05 Å) and one longer (1.55 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fourth H1+ site, H1+ is bonded in a distorted bent 150 degrees geometry to two O2- atoms. There is one shorter (1.04 Å) and one longer (1.53 Å) H–O bond length. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the sixth H1+ site, H1+ is bonded in a linear geometry to two O2- atoms. There is one shorter (1.02 Å) and one longer (1.53 Å) H–O bond length. In the seventh H1+ site, 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 a cornercorner with one CuO6 octahedra. The corner-sharing octahedral tilt angles are 52°. There are a spread of S–O bond distances ranging from 1.45–1.66 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 150 degrees geometry to one H1+ and one S6+ atom. In the second O2- site, O2- is bonded in a trigonal non-coplanar geometry to three H1+ atoms. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cu2+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Cu2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to three H1+ atoms. In the sixth O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to one H1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one O2- atom. The O–O bond length is 1.25 Å.
