Thallium(I) Salicylate and Phthalate: Syntheses and Structural Characterization

Abstract

Two new 2D polymers, thallium(I) hydrogensalicylate (1) and hydrogenphthalate (2), have been synthesized and characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopy. The single-crystal X-ray data show the coordination number of the TlI ions of compounds 1 and 2 to be four and six with the environment TlO4 and TlO6, respectively. The arrangement of the O atoms suggests a gap in the coordination geometry around the thallium atoms in both compounds, due to a stereo-chemically ‘active’ electron lone pair of TlI. There is another interaction between the thallium atom and the carbon atoms of an aromatic ring in compound 1, giving a total hapticity of ten with the environment C6O4Tl.
