Mn Al Tl Tl
MnTlTlAl crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one aluminum;thallium molecule and one MnTl cluster. In the MnTl cluster, Mn(1) is bonded in a single-bond geometry to one Tl(2) atom. The Mn(1)-Tl(2) bond length is 0.72 Å. Tl(2) is bonded in a single-bond geometry to one Mn(1) atom.
