PdSeTe crystallizes in the trigonal P3m1 space group. Pd(1) is bonded to three equivalent Te(1) and three equivalent Se(1) atoms to form PdTe3Se3 octahedra that share corners with three equivalent Te(1)Pd3Se3 octahedra, edges with three equivalent Te(1)Pd3Se3 octahedra, and edges with six equivalent Pd(1)Te3Se3 octahedra. The corner-sharing octahedral tilt angles are 17°. Te(1) is bonded to three equivalent Pd(1) and three equivalent Se(1) atoms to form distorted TePd3Se3 octahedra that share corners with three equivalent Pd(1)Te3Se3 octahedra, edges with three equivalent Pd(1)Te3Se3 octahedra, and edges with six equivalent Te(1)Pd3Se3 octahedra. The corner-sharing octahedral tilt angles are 17°. Se(1) is bonded in a 3-coordinate geometry to three equivalent Pd(1) and three equivalent Te(1) atoms.
