ReTl crystallizes in the orthorhombic Imma space group. Re(1) is bonded in a 10-coordinate geometry to two equivalent Re(1) and eight equivalent Tl(1) atoms. Tl(1) is bonded to eight equivalent Re(1) and four equivalent Tl(1) atoms to form a mixture of distorted edge, corner, and face-sharing TlTl4Re8 cuboctahedra.
ReTl crystallizes in the orthorhombic Imma space group. Re(1) is bonded in a 10-coordinate geometry to two equivalent Re(1) and eight equivalent Tl(1) atoms. Both Re(1)-Re(1) bond lengths are 2.48 Å. There are a spread of Re(1)-Tl(1) bond distances ranging from 3.05-3.15 Å. Tl(1) is bonded to eight equivalent Re(1) and four equivalent Tl(1) atoms to form a mixture of distorted edge, corner, and face-sharing TlTl4Re8 cuboctahedra. There are two shorter (3.04 Å) and two longer (3.10 Å) Tl(1)-Tl(1) bond lengths.
