Materials Data on KSr4(BO3)3 by Materials Project
KSr4(BO3)3 crystallizes in the orthorhombic Ama2 space group. The structure is three-dimensional. K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.87–3.12 Å. There are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.53–2.69 Å. In the second Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.59–2.97 Å. In the third Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.58–2.72 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.42 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.38 Å) and two longer (1.41 Å) B–O bond length. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.38 Å) and two longer (1.40 Å) B–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, three Sr2+, and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, four Sr2+, and one B3+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to four Sr2+ and one B3+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, four Sr2+, and one B3+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, three Sr2+, and one B3+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+, three Sr2+, and one B3+ atom.
