Abstract
ErLaS3 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. there are four inequivalent Er3+ sites. In the first Er3+ site, Er3+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing ErS6 octahedra. The corner-sharing octahedral tilt angles are 60°. There are a spread of Er–S bond distances ranging from 2.62–2.79 Å. In the second Er3+ site, Er3+ is bonded to six S2- atoms to form a mixture of edge and corner-sharing ErS6 octahedra. The corner-sharing octahedral tilt angles are 60°. There are a spread of Er–S bond distances ranging from 2.64–2.81 Å. In the third Er3+ site, Er3+ is bonded to seven S2- atoms to form a mixture of distorted face, edge, and corner-sharing ErS7 pentagonal bipyramids. There are a spread of Er–S bond distances ranging from 2.71–3.00 Å. In the fourth Er3+ site, Er3+ is bonded to seven S2- atoms to form a mixture of distorted face, edge, and corner-sharing ErS7 pentagonal bipyramids. There are a spread of Er–S bond distances ranging from 2.72–2.97 Å. There are four inequivalent La3+ sites. In the first La3+ site, La3+ is bonded in a 7-coordinate geometry to eight S2- atoms.
