Title: Materials Data on Ca3ZnGe5O14 by Materials Project

Abstract

Ca3ZnGe5O14 crystallizes in the monoclinic C2 space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.32–2.96 Å. In the second Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.32–2.91 Å. Zn2+ is bonded to six O2- atoms to form ZnO6 octahedra that share corners with four equivalent GeO4 tetrahedra. There are four shorter (2.11 Å) and two longer (2.14 Å) Zn–O bond lengths. There are three inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form distorted GeO4 tetrahedra that share corners with two equivalent ZnO6 octahedra and corners with two equivalent GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 66–68°. There are a spread of Ge–O bond distances ranging from 1.74–1.85 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form corner-sharing GeO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 1.72–1.81 Å. In the third Ge4+ site, Ge4+more » is bonded in a 4-coordinate geometry to four O2- atoms. There is two shorter (1.75 Å) and two longer (1.87 Å) Ge–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+, one Zn2+, and one Ge4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Ca2+ and two Ge4+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Ca2+ and two Ge4+ atoms. In the fourth O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+, one Zn2+, and one Ge4+ atom. In the fifth O2- site, O2- is bonded to three Ca2+ and one Ge4+ atom to form distorted corner-sharing OCa3Ge tetrahedra. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to one Ca2+, one Zn2+, and one Ge4+ atom. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Ca2+ and two Ge4+ atoms.« less
