Materials Data on Li2H10C8O7F18 by Materials Project

Li2C2H10O7(CF3)6 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of twenty-four fluoroform molecules and two Li2C2H10O7 clusters. In each Li2C2H10O7 cluster, there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.95–2.09 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted corner-sharing LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 1.94–2.11 Å. There are two inequivalent C+2.50+ sites. In the first C+2.50+ site, C+2.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.36 Å. In the second C+2.50+ site, C+2.50+ is bonded in a single-bond geometry to one O2- atom. The C–O bond length is 1.36 Å. There are ten inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.00 Å) and one longer (1.75 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. In the third H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.97 Å. In the fifth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.66 Å) H–O bond length. In the sixth H1+ site, H1+ is bonded in a distorted single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.66 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 0.97 Å. In the eighth 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 ninth 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 tenth H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 1.00 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, one C+2.50+, and two H1+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Li1+, one C+2.50+, and one H1+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and two H1+ atoms. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two H1+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two H1+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+ and two H1+ atoms. In the seventh O2- site, O2- is bonded in a distorted tetrahedral geometry to two Li1+ and two H1+ atoms.
