The reaction of bis(triphenyl)tin oxide, (Ph3Sn)2O, with 2,6-diisopropylphenylphosphate, (ArO)PO3H2 (Ar = 2,6-i-Pr2-C6H3), leads to the formation of a novel double-bicapped hexanuclear monoorganooxotin cage, [(PhSn)6(μ-OH)2(μ3-O)2(μ-OEt)4{(ArO)PO3}4]. This reaction proceeds by a de-arylation reaction involving the cleavage of Sn−C bonds.
