Materials Data on Ba5Al5Pb by Materials Project
Ba5Al5Pb crystallizes in the hexagonal P-6m2 space group. The structure is three-dimensional. there are three inequivalent Ba sites. In the first Ba site, Ba is bonded in a 9-coordinate geometry to six Al and three equivalent Pb atoms. There are three shorter (3.74 Å) and three longer (3.79 Å) Ba–Al bond lengths. All Ba–Pb bond lengths are 4.19 Å. In the second Ba site, Ba is bonded in a 1-coordinate geometry to nine Al and one Pb atom. There are three shorter (3.53 Å) and six longer (3.61 Å) Ba–Al bond lengths. The Ba–Pb bond length is 3.70 Å. In the third Ba site, Ba is bonded to two equivalent Al and three equivalent Pb atoms to form corner-sharing BaAl2Pb3 trigonal bipyramids. Both Ba–Al bond lengths are 3.63 Å. All Ba–Pb bond lengths are 3.53 Å. There are two inequivalent Al sites. In the first Al site, Al is bonded in a 10-coordinate geometry to seven Ba and three equivalent Al atoms. All Al–Al bond lengths are 2.74 Å. In the second Al site, Al is bonded in a distorted q6 geometry to six Ba and four Al atoms. Both Al–Al bond lengths are 2.84 Å. Pb is bonded to eleven Ba atoms to form distorted face-sharing PbBa11 trigonal bipyramids.
