Reactions
of Ph2SbCl3 with RSi(OH)3 [where
R = tert-Bu, cyclo-C6H11] and Ph2Si(OH)2 in toluene
in the presence of triethylamine as a base were
performed. Single-crystal X-ray structural elucidation of the products
revealed the formation of hexanuclear antimony(V) and mixed-valent
antimony (III/V) oxo-hydroxo clusters built up of an incomplete cubane
subunit. Interestingly, in all the reactions, at least one Sb–C
bond cleavage has been observed, leading to the formation of novel
cluster assemblies [(Ph2Sb)4(PhSb)2(C4H9SiO3)2(O)6(OH)2] (1), [(Ph2Sb)4(PhSb)2(C6H11SiO3)2(O)6(OH)2] (2), [(Ph2Sb)(PhSb)2(Ph2SiO2)2(O)3(OH)2]−Et3NH+ (3), and [(Ph2Sb)4(Sb)2(Ph2SiO2)2(O)6(OH)2] (4), respectively.
