Two Organic Diselenides: Dimesityl Diselenide and Bis(2,4,6-triisopropylphenyl) Diselenide

The organic diselenides, dimesityl diselenide [C₁₈H₂₂Se₂, (I)] and bis(2,4,6-triisopropylphenyl) diselenide [C₃₀H₄₆Se₂, (II)], display normal diselenide geometries: Se-Se bond lengths are 2.3341 (6) in (I) and 2.3389 (6) Å in (II), and the absolute C-Se-Se-C torsion angles are 83.96 (12) in (I) and 73.38 (16)° in (II).
