Preparation and characterization of copper sulfide nanoparticles from symmetrical [(Bu)_2NC(S)NC(O)C_6H_3(3,5- NO_2)_2]_2Cu(II) and [(Bu)_2NC(S)NC(O)C_6H_4(4-NO_2)]_2Cu(II) complexes by thermolysis

摘要

Trigonal copper sulfide nanoparticles were synthesized from symmetrical [(Bu)_2NC(S)NC(O)C_6H_3(3,5- NO_2)_2]_2Cu(II) and [(Bu)_2NC(S)NC(O)C_6H_4(4-NO_2)]_2Cu(II) complexes by thermolysis in the presence of surfactant oleylamine. The symmetrical copper complexes were synthesized by reaction of copper(II) acetate with N-(3,5-dinitrobenzoyl)-N', N'-dibutylthiourea and N-(4-nitrobenzoyl)-N', N'-dibutylthiourea. The symmetrical copper complexes were characterized by FT-IR spectroscopy, elemental analysis, and mass spectrometry (MS-APCl). The single-crystal X-ray structure of [(Bu)_2NC(S)NC(O)C_6H_4(4-NO_2)]_2Cu(II) has been determined from single-crystal X-ray diffraction data. These metal complexes have been used as single source precursors for the preparation of copper sulfide nanoparticles. The deposited copper sulfide nanoparticles were characterized by X-ray powder diffraction and transmission electron microscopy.
