The authors have used newly derived synthetic approaches to form several pyridine N-oxide phosphonates; they have fully characterized these new species; they have studied their coordination chemistry toward several lanthanide and actinide ions; and they have initiated solvent extraction studies of two ligands. The results for most of this work are described in three manuscripts that have been submitted or soon will be submitted for publication. In addition to that work the authors have also embarked on a major effort to survey the utility of computer assisted molecular modeling for the design of new chelating ligands for actinide ions. Finally, during this period the authors began to prepare large samples of selected ligands that will be used in future collaborative studies of extraction properties. It is expected that several of the new ligands will have superior extraction properties compared to existing chelate systems
