BeY4Re is Copper structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three BeY4Re clusters. Be(1) is bonded in a single-bond geometry to one Re(1) atom. The Be(1)-Re(1) bond length is 1.46 Å. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 2-coordinate geometry to one Y(2), two equivalent Y(1), and one Re(1) atom. The Y(1)-Y(2) bond length is 0.78 Å. Both Y(1)-Y(1) bond lengths are 0.45 Å. The Y(1)-Re(1) bond length is 1.30 Å. In the second Y site, Y(2) is bonded in a 3-coordinate geometry to three equivalent Y(1) atoms. Re(1) is bonded in a distorted rectangular see-saw-like geometry to one Be(1) and three equivalent Y(1) atoms.
