摘要
The combination of EuCl3. 6H(2)O with the trifunctional ligand 2,6-[(C6H5)(2)P(O)CH2](2)C5H3NO. in a 1:2 ratio, produces the coordination complex [Eu{[(C6H5)(2)P(O)CH2](2)C5H3NO} (2)(H2O)(2)]Cl-3. 9H(2)O. The molecular structure of the complex has been determined by single-crystal X-ray diffraction methods. The. N,P,P'-trioxide ligands each bind to the central Eu(III) ion in a tridentate fashion along with two water molecules. The eight inner sphere oxygen atoms surrounding the Eu(III) ion form a square antiprism. These results are discussed in the context of the structures formed by lanthanide nitrates.
