Materials Data on La2UO6 by Materials Project
La2UO6 crystallizes in the orthorhombic Immm space group. The structure is three-dimensional. U6+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are four shorter (2.16 Å) and four longer (2.34 Å) U–O bond lengths. La3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.45–2.52 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to one U6+ and three equivalent La3+ atoms to form a mixture of distorted edge and corner-sharing OLa3U tetrahedra. In the second O2- site, O2- is bonded to two equivalent U6+ and two equivalent La3+ atoms to form a mixture of edge and corner-sharing OLa2U2 tetrahedra.
