KYTe2 is Caswellsilverite structured and crystallizes in the trigonal R-3m space group. K(1) is bonded to six equivalent Te(1) atoms to form distorted KTe6 octahedra that share corners with six equivalent Y(1)Te6 octahedra, edges with six equivalent K(1)Te6 octahedra, and edges with six equivalent Y(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 9°. Y(1) is bonded to six equivalent Te(1) atoms to form YTe6 octahedra that share corners with six equivalent K(1)Te6 octahedra, edges with six equivalent K(1)Te6 octahedra, and edges with six equivalent Y(1)Te6 octahedra. The corner-sharing octahedral tilt angles are 9°. Te(1) is bonded to three equivalent K(1) and three equivalent Y(1) atoms to form a mixture of edge and corner-sharing TeK3Y3 octahedra. The corner-sharing octahedra are not tilted.
