The nucleophilic substitution of the reactive chlorine atoms of the n-butylboron-capped hexachlorine-containing clathrochelate precursor with the thiol-terminated closo-decaborate (PPh4)(2)[B10H9OCH2CH2OCH2CH2SH] in the presence of triethylamine afforded the closo-decaborate-containing clathrochelate dodecaanion [Fe{[(B10H9OCH2CH2OCH2CH2S)(2)Gm](3)-(BBun)(2)}](12-), which was isolated in the form of its tetraphenylphosphonium and sodium salts. The complexes obtained were characterized using elemental analysis, UV-VIS, H-1, B-11, and C-13{H-1} NMR, and IR spectroscopies.
