The material described by Tl3TaS4 crystallizes in the cubic I-43m space group. The structure consists of a Tl3TaS4 framework. Ta(1) is bonded in a tetrahedral geometry to four equivalent S(1) atoms. Tl(1) is bonded in a 4-coordinate geometry to four equivalent S(1) atoms. S(1) is bonded in a distorted single-bond geometry to one Ta(1) and three equivalent Tl(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
