Tripodal Tricarboxylic Acids on the Triphenylphosphine Oxide Platform
摘要
Abstract
New tripodal tricarboxylic acids on the triphenylphosphine oxide platform [2-HO(O)C(CH2)nOC6H4]3PO with different linker length (n = 1, 3) have been prepared. Their composition and structure have been determined by elemental analysis, IR and multinuclear (1H, 13C, 31P) NMR spectroscopy, and X-ray diffraction analysis. The complexes of the tripodal ligands with La(III) have been prepared; their composition and structure have been investigated by means of elemental analysis and IR spectroscopy.
