Abstract

The synthesis and characterisation of Sn(IV) halides, Ge(IV),
Ti(IV) and Zr(IV) chloride complexes of the type MX4 : Li_ 2 with
5-aminoindazole has been made. The possible structure of these
complexes has been proposed on the basis of elemental analysis
and infrared spectroscopy. The IR spectra suggest unidentate
behaviour of the ligand involving pyrrole nitrogen in all the cases
except the tin(IV) bromide complex, where the ligand exhibits its
bidentate nature, involving the pyridyl nitrogen. An octahedral
geometry has been proposed for all the complexes. In the case
of MX4 :'L type complexes, except for SnBr4 : L, an octahedral
halogen bridged structure has been proposed.
