Materials Data on K2Ge3(BO5)2 by Materials Project
Abstract
K2Ge3(BO5)2 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 2-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.76–3.38 Å. In the second K1+ site, K1+ is bonded in a 5-coordinate geometry to ten O2- atoms. There are a spread of K–O bond distances ranging from 2.77–3.41 Å. There are two inequivalent B3+ sites. In the first B3+ site, B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with four GeO4 tetrahedra. There is three shorter (1.49 Å) and one longer (1.50 Å) B–O bond length. In the second B3+ site, B3+ is bonded to four O2- atoms to form BO4 tetrahedra that share corners with four GeO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.48–1.50 Å. There are four inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent BO4 tetrahedra and corners with two equivalent GeO4 tetrahedra. There is two shorter (1.75 Å) and two longer (1.79 Å)more »
