Coordination and metal ion-mediated transformation of a polydentate ligand containing oxime, hydrazone and picolinoyl functionalities

An organic ligand containing oxime, hydrazone and picolinoyl donor groups forms an interesting dinuclear Pr(III) complex and undergoes a Dy(III)-assisted transformation in basic media to form a new polydentate ligand with two picolinoyl and two hydrazone functionalities.78
