Six new cyanide-bridged complexes (0–3D) have been assembled by employing one copper compound and six cyano precursors. Investigation of the magnetic properties revealed the ferro- or antiferromagnetic coupling between FeIII/CrI ion and CuII ion.

3D Framework

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.

Catecholase Activity

An N2O donor reduced Schiff base in presence of Ni(ClO4)2·6H2O and SCN− transforms into N2O2 donor ligand via deaminative coupling. Metal complexes 1 and 3 exhibit catecholase like activity and antiferromagnetic coupling between the Ni(ii) ions.

Two cyanide-bridged enantiopure one-dimensional single chain complexes have been synthesized and structurally characterized. Systematically magnetic investigations show the antiferromagnetic coupling between the Mn(iii)–Fe(iii) centers and the metamagnetic behavior at about 5.0 K.
