The Materials Project

UY6O12 crystallizes in the trigonal R-3 space group. The structure is three-dimensional. U6+ is bonded in an octahedral geometry to six equivalent O2- atoms. All U–O bond lengths are 2.10 Å. Y3+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Y–O bond distances ranging from 2.23–2.79 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one U6+ and three equivalent Y3+ atoms. In the second O2- site, O2- is bonded to four equivalent Y3+ atoms to form a mixture of edge and corner-sharing OY4 tetrahedra.
