A Novel 3D Heteronuclear (Cu(II) and Mg(II)) Coordination Polymer: Synthesis, Crystal Structure, and Catalytic Activity in the Formation of 1,2,3‐Triazoles

ABSTRACT In the current study, the heteronuclear coordination polymer C 12 H 18 Cu 2 MgO 12 was synthesized in crystalline form using the gradual evaporation method and utilized as a precursor for the synthesis of CuO/MgO mixed nano‐oxide. The crystal structure and thermal stability of the polymer were confirmed. Following the calcination of the polymer compound at 500°C, CuO/MgO mixed nano‐oxide were synthesized. The morphology and structure of the nanopowders were characterized through FE‐SEM, EDX, XRD, FT‐IR, VSM, XPS, ICP‐OES, and TEM techniques. Ultimately, the nanopowders were employed as catalysts in the azide–alkyne cycloaddition reaction. With very low leaching of copper (2.40 ppm) and magnesium ions (0.52 ppm), CuO/MgO nanocatalyst recycling and reuse were achieved for up to five cycles.
