Reaction of Elemental Sulfur with a Copper(I) Complex Forming a trans-μ-1,2 End-On Disulfide Complex: New Directions in Copper−Sulfur Chemistry

Elemental sulfur (S8) was found to react with [(TMPA)CuI(CH3CN)]+ to form the trans-μ-1,2 end-on disulfide complex [(TMPA)Cu−S−S−Cu(TMPA)]2+. The X-ray structure of this centrosymmetric disulfide complex shows a Cu(1)−S(1) bond length of 2.280(2) A and a S(1)−S(1A) bond length of 2.044(4) A.
