Two new coordination polymers,{[Co（O2N-Hbtb）（phen）（H2O）3]·2H2O}n 1 and {[Cu3（O2N-btb）2（bipy）2（H2O）4]·4H2O}n 2（O2N-H3btb=5-nitro-1,2,3-benzenetricarboxylic acid,phen=1,10-phenanthroline,bipy=2,2＇-bipyridine）,were prepared through hydrothermal reactions of Co（Ⅱ） or Cu（Ⅱ） salt with O2N-H3btb in the presence of different auxiliary N-donor *** crystal structures were determined by single-crystal X-ray diffraction analysis and further characterized by elemental analysis and IR *** the two complexes,O2N-H3btb ligand acts as monodentate and bis-monodentate modes,*** 1 displays a two-dimensional layered structure through the inter-and intramolecular hydrogen bonding interactions while complex 2 has an O2N-btb bridged one-dimensional chain which is extended into a three-dimensional network by hydrogen bonding *** magnetic properties of complex 2 are investigated over the temperature range of 2～300 K and ferromagnetic interactions are observed.

Schiff bases are known to possess anticancer, antibacterial, antifungal, antitubercular, anti-inflammatory, antimicrobial and antimalarial properties. In this paper antibacterial studies against variety of plants and human pathogenic bacteria with eight newly synthesized Schiff bases and several intermediate silyl compounds have been reported. The antibacterial activities of the synthesized compounds were primarily determined by paper disc diffusion method. The minimum inhibitory concentration (MIC) of each compound was also determined by tube dilution process. Seven different human pathogenic bacteria and eighteen different plant pathogenic bacteria were used for the antibacterial activity studies. While all synthesized compounds have shown significant antibacterial activity, one intermediate silyl compound has shown remarkably high antibacterial property. 5-substituted derivatives have shown relatively higher activity than non-substituted compounds. Polar substituent which increases hydrophilicity may have a positive impact on the antibacterial property.

Synthesis of 5-Substituted 2, 9-Dimethyl-1,10-Phenanthroline Dialdehydes and Their Schiff Bases with Sulfur-Containing Amines

引用

International Journal of Organic Chemistry 2013年第3期3卷 214-219页

作者： Zinia Jaman Mohammad R. Karim Tasneem A. Siddiquee Aminul H. Mirza Mohamad A. Ali Chemistry Faculty of Science University Brunei Darussalam Brunei Darussalam Sudan Department of Chemistry Tennessee State University Nashville USA

Eight new Schiff bases of 5-nitro and 5-bromo-substituted 1,10-phenanthroline-2,9-dicarboxaldehydes with sulfur-containing amines, thiosemicarbazide, S-alkyl/aryl dithiocarbazates and 2-mercaptoaniline have been synthesized and characterized by a variety of spectroscopic methods. The condensation reactions of the dialdehydes with the amines were carried out both in the presence and absence of conc. sulfuric acid. A significant increase in yield of the Schiff bases was observed when the reactions were carried out in the presence of sulfuric acid.
