Tosylate cluster complexes (Bu4N)2[М6I8(O3SC6H4CH3)6] (M = Mo, W)
The reaction of (Bu4N)2[М6I14] with silver p-toluenesulfonate (tosylate) AgO3SC6H4CH3 affords iodide cluster complexes (Bu4N)2[М6I8(Рts)6] (М = Mo (I), W (II); Рts is tosylate anion CH3C6H4SO3). According to the X-ray diffraction data (СIF file CCDC no. 1027969), the molybdenum atoms in (Bu4N)2[Мo6I8(Рts)6] · 2Et2O · 2MeCN (I′) are coordinated via the monodentate mode by the tosylate ligands. The 1H NMR and mass spectrometry data show that in donor solvents the complexes undergo solvolysis followed by the substitution of the tosylate ligands by the solvent molecules, which is accompanied by changes in the electrochemical properties, as shown by the cyclic voltammetry data.
