Abstract

119Sn Mössbauer spectroscopy has shown that attempts to intercalate three aryltin compounds (Ph3SnCl, (Ph3Sn)2O, Ph2SnCl2) into the synthetic smectite clay laponite under ambient conditions result in the formation of tin(IV) oxide pillared clays. The Mössbauer data indicate that the effectiveness of conversion to tin(IV) oxide pillars is in the order Ph3SnCl> (Ph3Sn)2O>Ph2SnCl2.

The organic product of the pillaring reaction has been identified by13C m.a.s. n.m.r. spectroscopy as benzene trapped within the pillared clay. The pillaring in these new materials is achieved via neutral precursors rather than by sacrificial reaction of the exchanged cation. Measurements by A.C. conductivity measurements (12 Hz–100 kHz) show significant precursor related increases in conductivity for the new pillared materials as compared with sodium-exchanged laponite.
