Abstract

EuTm2Se4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Tm3+ sites. In the first Tm3+ site, Tm3+ is bonded to six Se2- atoms to form a mixture of corner and edge-sharing TmSe6 octahedra. The corner-sharing octahedra tilt angles range from 47–63°. There are a spread of Tm–Se bond distances ranging from 2.78–2.86 Å. In the second Tm3+ site, Tm3+ is bonded to six Se2- atoms to form a mixture of corner and edge-sharing TmSe6 octahedra. The corner-sharing octahedra tilt angles range from 47–63°. There are a spread of Tm–Se bond distances ranging from 2.80–2.86 Å. Eu2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Eu–Se bond distances ranging from 3.16–3.41 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to three Tm3+ and two equivalent Eu2+ atoms. In the second Se2- site, Se2- is bonded to three equivalent Tm3+ and two equivalent Eu2+ atoms to form distorted edge-sharing SeEu2Tm3 square pyramids. In the third Se2- site, Se2- is bonded in a 5-coordinate geometry to three Tm3+ and two equivalent Eu2+ atoms. In the fourth Se2- site,more »« less
