Materials Data on K2Eu2O3 by Materials Project
Abstract
K2Eu2O3 is Aluminum carbonitride-like structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. K1+ is bonded in a 3-coordinate geometry to four O2- atoms. There are a spread of K–O bond distances ranging from 2.85–3.28 Å. Eu2+ is bonded to four O2- atoms to form a mixture of corner and edge-sharing EuO4 tetrahedra. There are a spread of Eu–O bond distances ranging from 2.31–2.39 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four equivalent K1+ and two equivalent Eu2+ atoms to form corner-sharing OK4Eu2 octahedra. The corner-sharing octahedral tilt angles are 61°. In the second O2- site, O2- is bonded in a 5-coordinate geometry to two equivalent K1+ and three equivalent Eu2+ atoms.
