Novel 1D Mn(II) complexes containing aromatic dicarboxylic acids

Abstract

Three Mn(II) complexes of [MnL(Bipy)(H2O)] n (I), [Mn3(Phen)2(HL)2(L)2]n (II), and [Mn(Phen)2(HL)(OH)] (III), where L = 4,4′-(2-acetylpropane-1,3-diyl)dibenzoic acid, Bipy = 2,2′-bipyridine, and Phen = 1,10-phenanthroline, were hydrothermally synthesized and characterized by single crystal X-ray diffractions, infrared spectroscopy, thermogravimetric analyses, and magnetic analyses. Complexes I and II are one dimensional (1D) coordination polymers which can form the supramolecules with the help of the intermolecular hydrogen bond interactions. Finally, the lande factors are simulated by magentochemical analysis to be 2.15 and 1.80 for I and II with S = 5/2, respectively.
