Abstract
New complexes of lead(II) and zirconium(IV) withmeta-andpara-substituted benzeneseleninic acids are reported and characterized by chemical analyses, spectroscopic methods and conductivity and magnetic measurements. The complexes are of the Pb(XC6H4SeO2)2 and ZrO(XC6H4SeO2)2 type; for zirconium(IV), working with a 1:4 metal:ligand stoichiometrical ratio, invariably the oxy derivative was obtained. The i.r. spectral data suggest that the complexes contain RSeO 2 – ligands acting as bidentate in O,O -seleninato complexes, Where possible, a tentative stereochemistry for the complexes is discussed on the basis of the results obtained.
