Description

General description

Copper(II) sulfate pentahydrate (CuSO₄·5H₂O, Blue vitriol) is a hydrated copper(II) salt. It undergoes hydrothermal reactions with the tripodal ligands to afford metal-organic frameworks (MOFs). CuSO₄·5H₂O along with metallic copper was employed as a catalyst for the synthesis of different ligand-arm functionalized azoamides. On heating above 560°C, it decomposes to CuO.

Application

Copper(II) sulfate pentahydrate may be employed in the following studies:

As a catalyst for the acetylation of alcohols and phenols under solvent-free conditions.
To compose the electrolyte for the electrodeposition of Cu-Zn-Sn precursors, required for the preparation of Cu₂ZnSnS₄ (CZTS) thin films.
As catalyst for the dehydration of alcohols.

Syntheses, crystal structures and properties of novel copper(II) complexes obtained by reactions of copper(II) sulfate pentahydrate with tripodal ligands.

Three novel metal-organic frameworks (MOFs), [Cu(1)SO4].H2O (4), [Cu2(2)2(SO4)2].4H2O (5) and [Cu(3)(H2O)]SO4.5.5H2O (6), were obtained by hydrothermal reactions of CuSO4.5H2O with the corresponding ligands, which have different flexibility. The structures of the synthesized complexes were determined by single-crystal X-ray diffraction analyses.
