| Abstract: | Abstract 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 3S,S and 1:1 complexes Dy(3R,S )(NO3)3]·(Me2CO) and Yb(3R,S )(NO3)3]·(Me2CO) are described. In these complexes, the pentafunctional ligand 3 coordinates in a tridentate NOPOPO chelate mode. |
