  Abstract: Syntheses for the new multidentate   chelating ligands   ((6,6'-((1,4-diazepane-1,4-diyl)bis(methylene))bis(pyridine-6,2-diyl))bis(methy lene))bis(diphenylphosphine   oxide) (2) and   6,6'-((1,4-diazepane-1,4-diyl)bis(methylene))bis(2-((diphenylphosphoryl)methyl) pyridine   1-oxide) (3), based upon a 1,4-diazepane platform functionalized   with 2-(diphenylphosphinoylmethyl)pyridine P-oxide and   2-(diphenylphosphinoylmethyl)pyridine N,P-dioxide fragments,   resp., are reported. Results from the coordination chem. of the   ligands with selected lanthanide nitrates and Cu(BF4)2 are   outlined, and crystal structures for two complexes, [Cu(2)](BF4)2   and [Cu(3)](BF4)2, are described along with survey Eu(III) and   Am(III) solvent extn. anal., for 3.
