Materials Data on Sr(LuSe2)2 by Materials Project
Sr(LuSe2)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Sr–Se bond distances ranging from 3.19–3.44 Å. There are two inequivalent Lu3+ sites. In the first Lu3+ site, Lu3+ is bonded to six Se2- atoms to form a mixture of edge and corner-sharing LuSe6 octahedra. The corner-sharing octahedra tilt angles range from 48–61°. There are a spread of Lu–Se bond distances ranging from 2.79–2.86 Å. In the second Lu3+ site, Lu3+ is bonded to six Se2- atoms to form a mixture of edge and corner-sharing LuSe6 octahedra. The corner-sharing octahedra tilt angles range from 48–61°. There are a spread of Lu–Se bond distances ranging from 2.77–2.86 Å. There are four inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent Sr2+ and three Lu3+ atoms. In the second Se2- site, Se2- is bonded to two equivalent Sr2+ and three equivalent Lu3+ atoms to form a mixture of distorted edge and corner-sharing SeSr2Lu3 square pyramids. In the third Se2- site, Se2- is bonded in a 5-coordinate geometry to two equivalent Sr2+ and three Lu3+ atoms. In the fourth Se2- site, Se2- is bonded to two equivalent Sr2+ and three equivalent Lu3+ atoms to form a mixture of distorted edge and corner-sharing SeSr2Lu3 trigonal bipyramids.
