The reaction of Cu2+ ions from Y zeolite cavities with sodium 8-mercaptoquinolinate (tox) or 8-hydroxyquinolinate (ox) was studied in aqueous solutions by EPR and electronic absorption spectroscopy, X-ray powder diffraction measurements, and scanning electron microscopy. The Cu2+ ions migrate towards the support surface to form [Cu(tox)2] or [Cu(ox)2(H2O)2] complex crystals. Owing to the low solubility of the complex, grains of the [Cu(tox)2] crystallites gradually grow over the support surface. Better soluble than [Cu(tox)2], the [Cu(ox)2(H2O)2] complex crystallizes separately from the carrier in the form of long needles.
