Complexes of Some Group(IV) Metal Halides with 5-Aminoindazole
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 :\u27L type complexes, except for SnBr4 : L, an octahedral
halogen bridged structure has been proposed
Complexes of manganese(III) oxychlorosulphate with some nitrogen bases
717-718Manganese(III) oxychlorosulphate complexes of the type MnOSO3.Cl.L2 and MnOSO3Cl.L’ with monodentate (aniline, biphenyl amine, acetonitrile, pyridine, 3-amino-2-chloropyridine, 4-cyanopyridine, acridine) and bidentate ligands (2,2-bipyridyl and 1,10-phenanthroline) have been characterized on the basis of their elemental analysis, molar conductance, magnetic susceptibility measurements, infrared and electronic spectral data. These studies, corroborate the tridentate nature and lowering of C3v symmetry of the chlorosulphate group. The com lexes are of high-spin octahedral type as evidenced by agnetic moment values and electronic spectral bands
