Materials Data on K3TbGe3(HO5)2 by Materials Project
Abstract
K3TbGe3(HO5)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 1-coordinate geometry to three O2- atoms. There are one shorter (2.71 Å) and two longer (3.07 Å) K–O bond lengths. 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 2.73–3.22 Å. Tb3+ is bonded to six O2- atoms to form TbO6 octahedra that share corners with six GeO4 tetrahedra. There are a spread of Tb–O bond distances ranging from 2.21–2.36 Å. There are two 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 TbO6 octahedra and corners with two equivalent GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 4–55°. There are a spread of Ge–O bond distances ranging from 1.72–1.81 Å. In the second Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent TbO6 octahedra and a cornercorner with one GeO4 tetrahedra. The corner-sharing octahedra tilt angles rangemore »
