Title: Materials Data on K2La2B2O7 by Materials Project

Abstract

K2La2(BO3)2O crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of K–O bond distances ranging from 2.69–2.86 Å. In the second K1+ site, K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.70–3.01 Å. There are two inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.41–2.66 Å. In the second La3+ site, La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.38–2.79 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.38–1.42 Å. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of B–O bond distances ranging from 1.37–1.41 Å.more » There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three La3+ and one B3+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to four K1+, one La3+, and one B3+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to one K1+, three La3+, and one B3+ atom. In the fourth O2- site, O2- is bonded to four La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to three La3+ and one B3+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to four K1+, one La3+, and one B3+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to four K1+, one La3+, and one B3+ atom.« less
