We have discovered the existence of metal-insulator transition at ~220 K in the new thiospinel CuIr2S 4. The electrical conductivity, a, for sintered-powder specimens drops abruptly from 2×102 S,cm -1 to 5×10-1S'cm -1 at TM\_I-~220 K with decreasing temperature. At temperatures T<TM\_ I, CuIr2S 4 ex

Effects of X-ray irradiation on the crystal structure and the electrical resistance were examined at low temperatures for the insulating phase of spinel compound CuIr 2 S 4 . We found that the resistance decreases by more than five decades by irradiation at 8.5 K. The structural change from triclini
