Synthesis, crystal structures, magnetism and fluorescence of manganese(II) and copper(II) complexes based on 2,5-diketopiperazine-N,N′-diacetic acid ligands
Two novel 2,5-diketopiperazine-N,N′-diacetic acid-based (H2DPDA) metal complexes [Mn(DPDA)0.5(phen)2H2O]2Cl2·2H2O (1) and {[Cu(DPDA)(phen)H2O]·4H2O}n(2)(H2DPDA = 2,5-diketopiperazine-N,N′-diacetic acid, phen = phenanthroline) have been hydrothermally synthesized, and the relationship between magnetism, fluorescence and structure was investigated. Crystal structure analysis shows that (1) 1 and 2 belong to the triclinic crystal system, the p-1 space group; (2) 2 shows a 1-dimensional zigzag chain structure. Thermogravimetric analysis shows that the complex 1 has better stability than 2. Magnetic measurements show that 1 exhibits antiferromagnetism but 2 exhibits ferromagnetism. Fluorescence test shows that 1 and 2 have luminescent properties and emits blue fluorescence.
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.
