Materials Data on La2SO6 by Materials Project
La2O2SO4 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.39–2.87 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.48 Å) and two longer (1.50 Å) S–O bond length. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to two equivalent La3+ and one S6+ atom. In the second O2- site, O2- is bonded to four equivalent La3+ atoms to form a mixture of distorted edge and corner-sharing OLa4 tetrahedra. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent La3+ and one S6+ atom.
