ReOs3Al is Pb (Zr_0.50 Ti_0.48) O_3 structured and crystallizes in the trigonal R3m space group. The structure is zero-dimensional and consists of three ReOs3Al clusters. Re(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms. All Re(1)-Os(1) bond lengths are 1.63 Å. Os(1) is bonded in a 2-coordinate geometry to one Re(1) and one Al(1) atom. The Os(1)-Al(1) bond length is 2.31 Å. Al(1) is bonded in a 3-coordinate geometry to three equivalent Os(1) atoms.
