Materials Data on BaTaSe3 by Materials Project
BaTaSe3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Ba2+ is bonded to twelve equivalent Se2- atoms to form BaSe12 cuboctahedra that share corners with six equivalent BaSe12 cuboctahedra, corners with six equivalent TaSe6 octahedra, faces with eight equivalent BaSe12 cuboctahedra, and faces with six equivalent TaSe6 octahedra. The corner-sharing octahedral tilt angles are 21°. There are six shorter (3.59 Å) and six longer (3.64 Å) Ba–Se bond lengths. Ta4+ is bonded to six equivalent Se2- atoms to form TaSe6 octahedra that share corners with six equivalent BaSe12 cuboctahedra, faces with six equivalent BaSe12 cuboctahedra, and faces with two equivalent TaSe6 octahedra. All Ta–Se bond lengths are 2.63 Å. Se2- is bonded in a 6-coordinate geometry to four equivalent Ba2+ and two equivalent Ta4+ atoms.
