The material structure described by TaInSe2 crystallizes in the hexagonal P-6m2 space group. Ta(1) is bonded to six equivalent Se(1) atoms to form distorted edge-sharing TaSe6 pentagonal pyramids. In(1) is bonded in a linear geometry to two equivalent Se(1) atoms. Se(1) is bonded in a distorted rectangular see-saw-like geometry to three equivalent Ta(1) and one In(1) atom. is represented by the CIF file [CIF]
