ReTl4B crystallizes in the trigonal R3m space group. Re(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Tl(1) and one B(1) atom. All Re(1)-Tl(1) bond lengths are 2.16 Å. The Re(1)-B(1) bond length is 2.49 Å. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 5-coordinate geometry to one Re(1), one Tl(2), two equivalent Tl(1), and one B(1) atom. The Tl(1)-Tl(2) bond length is 1.74 Å. Both Tl(1)-Tl(1) bond lengths are 1.00 Å. The Tl(1)-B(1) bond length is 2.99 Å. In the second Tl site, Tl(2) is bonded in a 3-coordinate geometry to three equivalent Tl(1) atoms. B(1) is bonded in a distorted trigonal pyramidal geometry to one Re(1) and three equivalent Tl(1) atoms.
