摘要：

New halide-substituted cluster anions [Cd10S4X4(SR)(12)](4-) (R = Ph, X = I, 2a; R = p-MeC6H4, X = I, 3a or Br, 3b) of the [Cd10S4(SR)(16)](4-) family have been prepared and characterized; investigations of their luminescence show that the introduction of the halide groups produces red shifts and significant enhancements in their emission intensities.
