Copper(II) pyridine-2,6-dicarboxylate dihydrate and its ronicol (ron), nicotinamide (nia) and caffeine (caf) complexes were prepared and their spectral, magnetic as well as their bio-activites were studied. X-ray analysis of [Cu(pydca)(H2O)2] (pydca = pyridine- 2,6-dicarboxylate) shows, that the complex exists in two isomeric forms: monoclinic and triclinic and it is an example of the coordination isomerism. Triclinic forms also exists in two isomeric forms, differing mostly by degree of distortion and being an example of the distortion isomerism. On the basis of spectral and magnetic properties for Cu(pydca)L (L = ron, nia or caf) a square-pyramidal coordination of the copper(II) ion can be proposed. Highest bio-activity shows [Cu(pydca)(H2O)2].
