Europium polychelates on the basis of 1,2,4,5-benzenetetracarboxylic acid

Europium complexes with 1,2,4,5-benzene tetracarboxylic acid and neutral ligands Eu4(PM)3xnH2OxmL, where PM is an anion of pyrometallic acid, L is a neutral ligand: triphenylphosphine oxide, triisobutylphosphate, dimethyl formamide, phenanthroline, n=16, m=0; n=9, m=1.3 are synthesized. Individuality of the compounds has confirmed by elementary and X-ray diffraction analyses. The compounds are characterized by the methods of IR and luminescent spectroscopy, thermogravimetry. During coordination interacton with europium ions acidoligands uses four carboxylic groups with formation of a polymeric chain. It is established that two types of water molecules coordination-bonded with europium atom compose Eu4(PM)3x16H2O polychelate
