Materials Data on BaZnGeO4 by Materials Project
BaZnGeO4 crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. there are three inequivalent Ba2+ sites. In the first Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.85–3.03 Å. In the second Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.87–3.11 Å. In the third Ba2+ site, Ba2+ is bonded in a distorted q6 geometry to nine O2- atoms. There are a spread of Ba–O bond distances ranging from 2.80–3.20 Å. Zn2+ is bonded to four O2- atoms to form ZnO4 tetrahedra that share corners with four equivalent GeO4 tetrahedra. There are a spread of Zn–O bond distances ranging from 1.96–1.98 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with four equivalent ZnO4 tetrahedra. There is three shorter (1.77 Å) and one longer (1.78 Å) Ge–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Ba2+, one Zn2+, and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted linear geometry to three Ba2+, one Zn2+, and one Ge4+ atom. In the third O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ba2+, one Zn2+, and one Ge4+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Ba2+, one Zn2+, and one Ge4+ atom.
