Materials Data on La2Bi2O7 by Materials Project
Abstract
La2Bi2O7 crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. La3+ is bonded in a body-centered cubic geometry to eight O2- atoms. There are two shorter (2.44 Å) and six longer (2.66 Å) La–O bond lengths. Bi4+ is bonded to six equivalent O2- atoms to form distorted corner-sharing BiO6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Bi–O bond lengths are 2.25 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent La3+ and two equivalent Bi4+ atoms to form a mixture of distorted edge and corner-sharing OLa2Bi2 tetrahedra. In the second O2- site, O2- is bonded to four equivalent La3+ atoms to form a mixture of edge and corner-sharing OLa4 tetrahedra.
