Tin(II) and Tin(IV) Derivatives of Pyrogallol

摘要

SnA and (PyH)2SnA3have been isolated by the interaction of the dihydrate of tin(II) chloride and the pentahydrate of tin(IV) chloride, respectively, with pyrogallol (H2A) in the appropriate ratios. The stoichiometry of the complexes was determined by analysis and confirmed by potentiometric titrations. SnA and (PyH)2SnA3were characterized by IR and thermal analysis. A1H NMR study of (PyH)2SnA3as well as X-Ray powder pattern of both compounds are reported.
