Abstract

Two manganese(ii)-dihydroxyterephthalate complexes were obtained under solvothermal conditions: [Mn(H2dhtp)(H2O)2] n (1) and [Mn2(dhtp)(H2O)2] n (2) (H4dhtp = 2,5-dihydroxyterephthalate). The 3D framework of complex 1 is constructed by H2dhtp ligands joined to 1D carboxylate-bridged Mn(ii) chains, which features a (4,4)-connected PtS net. Complex 2 contains a novel inorganic honeycomb Mn(ii)–O layer, which is further connected into a 3D (4,8)-connected flu net by dhtp ligands. Magnetic measurements of 1 and 2 were performed in the range of 2–300 K and the results indicate that antiferromagnetic coupling exits in the manganese(ii) centres of both complexes.
