摘要

The Schiff base methyl 2-pyridyl ketone semicarbazone (HL) was prepared from the condensation of methyl 2-pyridyl ketone and semicarbazide, and used in the synthesis of a series of novel binuclear Cu(II) complexes with three distinct bridging ligands: [Cu(L)(μ_(1,1)-N_3)]_2 (1), [Cu(L)(μ_(S,N)-SCN)]_2 (2) and [Cu(L)(Cl)] _2 (3). The compounds were characterized by elemental analysis, IR and UV-Vis spectroscopy, and their solid-state structures have been established by single-crystal X-ray diffraction revealing the first binuclear complexes with the HL ligand. Supramolecular interactions invoving the adjacent complexes were studied in detail. The antimicrobial activity of HL and the complexes 1-3 was further investigated against the bacteria Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Erwinia carotovora and fungals Candida kefyr, Candida krusei and Aspergillus niger, with the complex 3 demonstrating enhanced activity relatively to the free ligand and remaining complexes.
