The crystal structure described by Al3Y crystallizes in the hexagonal P6_3/mmc space group. The structure is zero-dimensional and consists of two Al3Y clusters. Y(1) is bonded in a trigonal planar geometry to three equivalent Al(1) atoms. Al(1) is bonded in a distorted single-bond geometry to one Y(1) atom. is represented by the CIF file [CIF]
