CuS2CuS4Cu9S10(S)4 crystallizes in the trigonal R3m space group. The structure is two-dimensional and consists of three Cu9S10 sheets oriented in the (0, 0, 1) direction; three CuS2 sheets oriented in the (0, 0, 1) direction; three CuS4 sheets oriented in the (0, 0, 1) direction; and six S sheets oriented in the (0, 0, 1) direction.
