Abstract

The work contained in this thesis describes the crystal structures of a number of tin(IV) and
tellurium(IV) carboxylates and dithiocarbamates. The results show the regularity at which these
types of compounds form secondary bonds (weak interactions), and the effect of the lone pair of
tellurium(IV) on the geometries formed. The area has been studied through the determination of
the following crystal structures:

i) monocarboxylates: Ph3SnOCOCH2Cl, Ph3SnOCOCHCh, Ph3SnOCOCCh.MeOH.
Ph3SnOCOCCh and Ph3TeOCOCCh.

ii) dicarboxulates : Ph2Sn(OCOCH3)2, Ph2Sn(OCOCH2CI)2 and Ph2Te(OCOCCI3)2

iii) dithiocarbamates : Ph2Te(S2CNEt2)2, Ph2Te(S2CN(Et)(Ph))2 and Ph2Te(S2CNPh2)2

In addition to these, six hydrolysis products of Ph3SnOCOCCh are reponed. These com-
pounds show the varied results that are obtained from the facile dearylation of the organotin com-
pound by a strong organic acid in the presence of water. The following structures are reported:
Ph2 Sn(OH)(OCOCCh), {[Pb2Sn(OCOCCh)hOh (two isomers), [(PbSn))(Oh(OCOCCh)sh,
[PhSn(O)(OCOCCh)]6 and [(Ph 2 Sn)2(OH)(OCOCCh)3h.
