Abstract
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：
Transition Metal Chemistry is an international journal designed to deal with all aspects of the subject embodied in the title: the preparation of transition metal-based molecular compounds of all kinds (including complexes of the Group 12 elements), their structural, physical, kinetic, catalytic and biological properties, their use in chemical synthesis as well as their application in the widest context, their role in naturally occurring systems etc.
Manuscripts submitted to the journal should be of broad appeal to the readership and for this reason, papers which are confined to more specialised studies such as the measurement of solution phase equilibria or thermal decomposition studies, or papers which include extensive material on f-block elements, or papers dealing with non-molecular materials, will not normally be considered for publication. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures.
