Implication

Experimental study demonstrates the synthesis of a porous copper(II) crystal complex, indicating strong potential for small molecule sequestration and catalysis.

Key Points

  • Synthesize and characterize a novel distorted octahedral copper(II) complex with a tridentate Schiff base to assess its framework stability and gas capture capabilities.
  • Synthesized an NNO tridentate Schiff base ligand via condensation and coordinated it to copper(II) ions.
  • Characterized the crystal structure and thermal properties using single-crystal X-ray diffraction (SCXRD), FTIR, NMR (1H and 13C), ESI-MS, TGA/DTG, CHN elemental analysis, and Hirshfeld surface analysis.
  • Single-crystal X-ray diffraction revealed a stable 3D porous framework with an intrinsic pore size of 5.44 Å and a unit cell density of 996 atoms.
  • Hirshfeld surface analysis indicated that π–π stacking interactions between phenolic rings contribute 45% of the total non-covalent stabilizing forces.
  • The complex demonstrated high thermal stability, insolubility in water and mild alcohols, and suitable pore dimensions for trapping small molecules such as H2O, CH4, C2H6, C3H8, and CO2.
