A variety of surfactant-modified clusters with both straight-chain alkyl sulfonates, (Bu4N)2[W6Cl8(n-alkyl)6] (chain length=2-10), and branched alkyl sulfonates, (Bu4N)2[W6Cl8(t-butylSO3)6] and (Bu4N)2[W6Cl8(sec-butyl-SO3)6, have been synthesized. The clusters were prepared via substitution of the terminal chloride ligands in tungsten(II) chloride clusters via metathesis with the appropriate silver salt. The clusters have been characterized using FT-IR, Raman spectroscopy, 1H FT-NMR, and x-ray diffraction.
