Synthese und Kristallstruktur von [(n‐Bu)4N][W6Cl18]

Synthesis and Crystal Structure of (n‐Bu)₄N]W₆Cl₁₈] Single‐crystals of (n‐Bu)₄N]W₆Cl₁₈] were obtained as thin needles by adding methanol to a solution of W₆Cl₁₈ and (n‐Bu)₄N]Cl in tetrahydrofuran. The structure was determined by single‐crystal X‐ray diffraction at 210 K. (n‐Bu)₄N]W₆Cl₁₈] crystallizes in the monoclinic space group C 2/c with Z = 8 and the lattice parameters a = 2175.6(1) pm, b = 1738.0(1) pm, c = 2160.36(9) pm, and β = 91.680(5) °. The crystal structure contains isolated (W₆Cl₁₂ⁱ)Cl₆^a]^— clusters and (n‐Bu)₄N]⁺ ions.
