On the behaviour of organotin compounds with cyclodextrins: Part 1. The complex between allyl-di- n-butyltin chloride and β-cyclodextrin

A complex between allyl-di- n-butyltin chloride and β-cyclodextrin has been obtained in good yield by the coprecipitation method in aqueous solution at room temperature. The stoichiometry, determined by NMR and elemental analysis, was found to be 1:1. The complex was characterised by means of severa...

Summary:A complex between allyl-di- n-butyltin chloride and β-cyclodextrin has been obtained in good yield by the coprecipitation method in aqueous solution at room temperature. The stoichiometry, determined by NMR and elemental analysis, was found to be 1:1. The complex was characterised by means of several techniques, such as TGA, DSC, ESIMS, SEM, NMR, and Mössbauer spectroscopy. On the basis of these results, we suggest a structure for this complex where the tin derivative is included in the cyclodextrin, replacing about six of the ca. nine water molecules coordinated to it and where the metal centre displays a pentacoordination, probably due to Sn⋯O long range contacts with the hydroxyl groups of the rim of the macrocycle.
