Synthesis, characterization and crystallographic determination of symmetrical Schiff bases and their Zn(II) metal complexes
Two new tetradentate symmetrical Schiff bases derived from 2,2’-diamino-4,4’-dimethyl-1,1’-biphenyl or its dibromo substituted analog and 3,5-diiodosalicylaldehyde were synthesized. The reactions of these Schiff bases with zinc acetate generated the corresponding Zn(II)-complexes in which the zinc atom is bonded through the two azoimine nitrogen atoms in addition to the two oxygen atoms of the deprotonated hydroxyl groups. The Schiff bases and their Zn(II) complexes were characterized using UV-Vis, 1H- and 13C-NMR, IR spectroscopy and elemental analysis. The structures of the two Schiff bases as well as the two zinc(II) complexes were further approved by single crystal X-ray analysis.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
