Materials Data on BaCeC2O6F by Materials Project
Abstract
BaCe(CO3)2F crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three Ba(C1O3)2 sheets oriented in the (0, 0, 1) direction and three BaCe2C2(O3F)2 sheets oriented in the (0, 0, 1) direction. In each Ba(C1O3)2 sheet, Ba2+ is bonded in an octahedral geometry to six O2- atoms. All Ba–O bond lengths are 2.65 Å. There are two inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All C–O bond lengths are 1.30 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All C–O bond lengths are 1.30 Å. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Ba2+ and one C4+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Ba2+ and one C4+ atom. In each BaCe2C2(O3F)2 sheet, Ba2+ is bonded in a hexagonal planar geometry to six F1- atoms. There are three shorter (3.30 Å) and three longer (3.31 Å) Ba–F bond lengths. There are two inequivalent Ce3+ sites. In the first Ce3+ site, Ce3+more »
