Bis[2-(4′-Bromopyrazolyl-1′)-3-Tosylaminopyridinato]zinc(II): Synthesis, structure, and luminescence properties
摘要:
2-(4'-Bromopyrazolyl-1')-3-tosylaminopyridine (HL3) and its complex ZnL2 (I) are synthesized, and their structures are studied by IR, UV, and H-1 NMR spectroscopy. The molecular structure of complex ZnL2 is determined by X-ray diffraction analysis. The atomic structure of ZnL2 is confirmed by the optimization of the molecular geometry using quantum-chemical calculations in the density functional theory approximation. The experimental bands in the absorption spectrum of complex I are interpreted on the basis of the calculations, and its photoluminescence properties are studied.

Previously undescribed 2-, 4or 6-substituted hetaryl-3(5)-nitropyridines were synthesized by the interaction of a number of chlorosubstituted 3(5)-nitropyridines with some diazoles or 3-chloropyridazin-6one. In addition, pyrazolyl-3-nitropyridines were prepared by both the above method and cyclization of hydrazinopyridines, which, in turn, were synthesized by the treatment of chlorosubstituted 3-nitropyridines with hydrazine. It has been shown that these compounds have a moderate antibacterial activity against some pathogenic Gram-positive and Gram-negative bacteria (Staphylococcus aureus and Escherichia coli) and a strong protistocidal effect on protozoa species Colpoda steinii surpassing in this respect clinically used reference drugs.
