## Abstract The cluster [W~3~S~4~H~3~(dmpe)~3~]^+^ (1) (dmpe=1,2‐bis(dimethylphosphino)ethane) reacts with HX (X=Cl, Br) to form the corresponding [W~3~S~4~X~3~(dmpe)~3~]^+^ (2) complexes, but no reaction is observed when 1 is treated with an excess of halide salts. Kinetic studies indicate that th
