Materials Data on KSc(BH4)4 by Materials Project
KSc(BH4)4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. K1+ is bonded in a distorted rectangular see-saw-like geometry to four H+0.50+ atoms. There are a spread of K–H bond distances ranging from 2.72–2.83 Å. Sc3+ is bonded to twelve H+0.50+ atoms to form distorted ScH12 cuboctahedra that share faces with four BH4 tetrahedra. There are a spread of Sc–H bond distances ranging from 2.13–2.25 Å. There are three inequivalent B3- sites. In the first B3- site, B3- is bonded to four H+0.50+ atoms to form BH4 tetrahedra that share a faceface with one ScH12 cuboctahedra. There are a spread of B–H bond distances ranging from 1.20–1.24 Å. In the second B3- site, B3- is bonded to four H+0.50+ atoms to form BH4 tetrahedra that share a faceface with one ScH12 cuboctahedra. There is one shorter (1.20 Å) and three longer (1.24 Å) B–H bond length. In the third B3- site, B3- is bonded to four H+0.50+ atoms to form BH4 tetrahedra that share a faceface with one ScH12 cuboctahedra. There are a spread of B–H bond distances ranging from 1.21–1.24 Å. There are ten inequivalent H+0.50+ sites. In the first H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Sc3+ and one B3- atom. In the second H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one K1+ and one B3- atom. In the third H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one K1+ and one B3- atom. In the fourth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Sc3+ and one B3- atom. In the fifth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Sc3+ and one B3- atom. In the sixth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one K1+ and one B3- atom. In the seventh H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Sc3+ and one B3- atom. In the eighth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one Sc3+ and one B3- atom. In the ninth H+0.50+ site, H+0.50+ is bonded in a single-bond geometry to one Sc3+ and one B3- atom. In the tenth H+0.50+ site, H+0.50+ is bonded in a distorted single-bond geometry to one Sc3+ and one B3- atom.
