Materials Data on Tm2Cu2O5 by Materials Project
Abstract
Tm2Cu2O5 is Spinel-like structured and crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are two inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TmO6 octahedra. The corner-sharing octahedra tilt angles range from 20–64°. There are a spread of Tm–O bond distances ranging from 2.20–2.27 Å. In the second Tm3+ site, Tm3+ is bonded to six O2- atoms to form a mixture of edge and corner-sharing TmO6 octahedra. The corner-sharing octahedra tilt angles range from 20–64°. There are a spread of Tm–O bond distances ranging from 2.20–2.28 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.94–2.02 Å. In the second Cu2+ site, Cu2+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.94–2.01 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to three Tm3+ and one Cu2+ atom to form distorted OTm3Cu tetrahedra that sharemore »
