Reactions of some metal ions with certain Schiff bases and their precursors

Schiff base complexes with two or three nitrogen donor atoms have recently attracted interest in virtue of their biological activity. 2,6-Pyridinedicarboxaldehyde lends itself to the formation of a host of such Schiff bases. The present work has therefore been devoted to the investigation of the synthesis and reactions of Schiff bases derived from 2,6-pyridinedicarboxaldehyde. (...continues)
