276ChemInform Abstract The catechol ligands are prepared by condensation of 2,3-dihydroxybenzaldehyde with the corresponding aminoalkylpyridine and react in ethanol with the appropriate copper salts to yield the complexes (I)-(III) (no yields given). The X-ray structure of (I) is determined (space group P1, Z=2). A novel mode of coordination of the ligand is observed. From the magnetic and IR spectroscopic characterization of the complexes it is concluded that (III) probably possesses the same structure as (I). On the other hand, the complexes (II) behave in a manner similar to that of their salicylaldehyde analogues.
