Terbium copper disulfide, TbCuS2, has been synthesized in the reaction of the elements in a KI flux at 850 ℃. The compound crystallizes in space group P21/c of the monoclinic system with four formula units in a cell of dimensions of a= 0.639 3(1) nm, b=0.702 5(1) nm, c=0.670 8(1) nm, β=98.097(4)°, and V=0.298 3(1) nm3 at 153 K. The structure comprises two-dimensional 2∞[CuS2] layers along [100] separated by the Tb atoms. In the structure, each Tb and Cu atoms are coordinated to seven and four S atoms, respectively.
