The crystal structure described by Eu3S4 crystallizes in the cubic I-43d space group. Eu(1) is bonded to eight equivalent S(1) atoms to form a mixture of distorted edge, face, and corner-sharing EuS8 hexagonal bipyramids. S(1) is bonded to six equivalent Eu(1) atoms to form a mixture of distorted edge, face, and corner-sharing SEu6 octahedra. The corner-sharing octahedral tilt angles range from 18-49°. is represented by the CIF card [CIF]
