Materials Data on Dy2Cu(GeO3)4 by Materials Project
Dy2Cu(GeO3)4 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Dy3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Dy–O bond distances ranging from 2.26–2.59 Å. Cu2+ is bonded in a square co-planar geometry to four O2- atoms. All Cu–O bond lengths are 1.98 Å. There are two inequivalent Ge4+ sites. In the first 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 1.76–1.80 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 1.75–1.82 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Dy3+ and one Ge4+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Dy3+ and one Ge4+ atom. In the third O2- site, O2- is bonded in a 2-coordinate geometry to one Dy3+ and two Ge4+ atoms. In the fourth O2- site, O2- is bonded in a bent 120 degrees geometry to two Ge4+ atoms. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Dy3+, one Cu2+, and one Ge4+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Dy3+, one Cu2+, and one Ge4+ atom.
