Materials Data on Eu2Re6S11 by Materials Project
Eu2Re6S11 crystallizes in the trigonal R-3c space group. The structure is three-dimensional. Eu2+ is bonded in a 10-coordinate geometry to ten S2- atoms. There are a spread of Eu–S bond distances ranging from 2.96–3.54 Å. Re3+ is bonded to five S2- atoms to form a mixture of edge and corner-sharing ReS5 square pyramids. There are a spread of Re–S bond distances ranging from 2.40–2.50 Å. There are three inequivalent S2- sites. In the first S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent Eu2+ and three equivalent Re3+ atoms. In the second S2- site, S2- is bonded in a 4-coordinate geometry to two equivalent Eu2+ and two equivalent Re3+ atoms. In the third S2- site, S2- is bonded in a 7-coordinate geometry to one Eu2+ and three equivalent Re3+ atoms.
