The synthesis and spectroscopic characterization of the first silylated mixed‐chalcogen reagent, Me 3 Si–SeS–SiMe 3 , is presented. This reagent is shown to be an effective and efficient delivery source of both sulfur and selenium as demonstrated in the synthesis of a [Cu 84 Se 42– x S x (PEt 2 Ph) 24 ] ( x ≈ 15) cluster. The reaction proceeds with chalcogen‐chalcogen bond cleavage and the resulting X‐ray crystal structure of [Cu 84 Se 42– x S x (PEt 2 Ph) 24 ] illustrates the intimate mixing of sulfur and selenium within the cluster core.
