Materials Data on VH12SO10 by Materials Project
V(H2O)6VH12(SO7)2 crystallizes in the monoclinic C2/c space group. The structure is one-dimensional and consists of four V(H2O)6 clusters and four VH12(SO7)2 ribbons oriented in the (0, 1, 0) direction. In each V(H2O)6 cluster, V2+ is bonded in an octahedral geometry to six O2- atoms. There are four shorter (2.16 Å) and two longer (2.18 Å) V–O bond lengths. 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 0.99 Å. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.98 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one V2+ and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted water-like geometry to one V2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a distorted water-like geometry to one V2+ and two H1+ atoms. In each VH12(SO7)2 ribbon, V2+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 2.15–2.21 Å. 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 two O2- atoms. There is one shorter (0.99 Å) and one longer (1.73 Å) H–O bond length. In the third H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.66 Å) H–O bond length. 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 O2- atom. The H–O bond length is 0.99 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.49 Å) and two longer (1.50 Å) S–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. In the second O2- site, O2- is bonded in a distorted water-like geometry to one V2+ and two H1+ atoms. In the third O2- site, O2- is bonded in a single-bond geometry to one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to one V2+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to two H1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted water-like geometry to one V2+ and two H1+ atoms.
