A two-step synthesis for 2,6-bis[(diphenyl)-N,N-diethylcarbamoylmethylphosphine oxide]pyridine N-oxide (3) from 2,6-bis[(diphenylphosphinoyl)methyl]pyridine is reported along with coordination chemistry with Dy(III) and Yb(III). Crystal structure determinations for the ligand 3(S,S) and 1:1 complexes [Dy(3(R,S))(NO3)(3)](Me2CO) and [Yb(3(R,S))(uNO(3))(3)](Me2CO) are described. In these complexes, the pentafunctional ligand 3 coordinates in a tridentate NOPOPO chelate mode.
