Abstract
YbAl3C3 crystallizes in the hexagonal P6_3/mmc space group. The structure is three-dimensional. Yb3+ is bonded to six equivalent C4- atoms to form YbC6 octahedra that share corners with six equivalent AlC4 tetrahedra, edges with six equivalent YbC6 octahedra, and edges with six equivalent AlC4 tetrahedra. All Yb–C bond lengths are 2.63 Å. There are two inequivalent Al3+ sites. In the first Al3+ site, Al3+ is bonded in a trigonal planar geometry to three equivalent C4- atoms. All Al–C bond lengths are 1.98 Å. In the second Al3+ site, Al3+ is bonded to four C4- atoms to form AlC4 tetrahedra that share corners with three equivalent YbC6 octahedra, corners with seven equivalent AlC4 tetrahedra, and edges with three equivalent YbC6 octahedra. The corner-sharing octahedral tilt angles are 24°. There are one shorter (2.03 Å) and three longer (2.07 Å) Al–C bond lengths. There are two inequivalent C4- sites. In the first C4- site, C4- is bonded in a 3-coordinate geometry to three equivalent Yb3+ and three equivalent Al3+ atoms. In the second C4- site, C4- is bonded to five Al3+ atoms to form corner-sharing CAl5 trigonal bipyramids.
