description: K2UC2H6SO13 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.70–3.21 Å. In the second K1+ site, K1+ is bonded in a 6-coordinate geometry to one H1+ and eight O2- atoms. The K–H bond length is 2.93 Å. There are a spread of K–O bond distances ranging from 2.69–3.20 Å. U4+ is bonded to seven O2- atoms to form distorted UO7 pentagonal bipyramids that share a cornercorner with one SO4 tetrahedra. There are a spread of U–O bond distances ranging from 1.80–2.49 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. Both C–O bond lengths are 1.27 Å. In the second C4+ site, C4+ is bonded in a bent 120 degrees geometry to two O2- atoms. There is one shorter (1.26 Å) and one longer (1.27 Å) C–O bond length. There are six 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 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 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 single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. 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 single-bond geometry to one K1+ and 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 UO7 pentagonal bipyramid. There are a spread of S–O bond distances ranging from 1.47–1.56 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one U4+ and one C4+ atom. In the second O2- site, O2- is bonded in a single-bond geometry to one U4+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one U4+ and one C4+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a water-like geometry to two K1+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one K1+, one U4+, and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a water-like geometry to two equivalent K1+ and two H1+ atoms. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one U4+ and one C4+ atom. In the tenth O2- site, O2- is bonded in a water-like geometry to two K1+ and two H1+ atoms. In the eleventh O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, one U4+, and one C4+ atom. In the thirteenth O2- site, O2- is bonded in a single-bond geometry to one U4+ atom.
