The compound described by Tm4Al is Iron carbide-like structured and crystallizes in the cubic Fd-3m space group. The structure is zero-dimensional and consists of eight Tm4Al clusters. Tm(1) is bonded in a single-bond geometry to one Al(1) atom. Al(1) is bonded in a tetrahedral geometry to four equivalent Tm(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
