Diversity in magnetic properties of 3D isomorphous networks of Co(II) and Mn(II) constructed by napthalene-l,4-dicarboxylate

摘要

Two novel 3D isomorphous organic-inorganic hybrid frameworks, [M(l,4-napdc)]_n ( M = Co(II), 1 and Mn(II), 2; 1,4-napdcH_2 = napthalene-l,4-dicarboxylic acid) have been hydrothermally synthesized and structurally characterized, and the magnetic results exhibit metamagnetic behaviour (T_C = 5.5 K) for 1, and a weak antiferromagnetic interaction for 2, which are structurally correlated.The chemistry of multifunctional metal-organic hybrid frameworks is recently one of the most productive areas of chemical research.Currently a challenging target is the design and synthesis of molecule based magnetic materials with the strategic co-existance of multiple properties,like spin-crossover,optical properties and porous functionality.
