Molecular and Crystal Structure of the C₆₀F₁₈ Adducts with Bromine and Carbon Disulfide

Abstract

No reaction occurs between C₆₀F₁₈ and liquid bromine. Instead, the solvate, C₆₀F₁₈·2Br₂ was isolated. The solvate C₆₀F₁₈·0.5CS₂ was prepared from solution of C₆₀F₁₈ in carbon disulfide. Crystal structures of the both solvates have been determined by single crystal X‐ray diffraction. C₆₀F₁₈ molecules have geometrical parameters similar to those in the known solvates and solvent free compound. The crystal packing consists of distorted hexagonal layers of the C₆₀F₁₈ molecules. Br₂ molecules occupy tetrahedral holes between the layers. CS₂ molecules occupy half of octahedral holes.
