A 3D heteropolynuclear network with 4,6-connected (44 · 62)(48 · 66 · 8) topology: Synthesis, structure, thermal and magnetic properties

This paper describes a novel heteropolynuclear coordination polymer [Cd4Co2(m-BDC)6(HIm)4]n (1) (m-H2BDC = 1,3-benzenedicarboxylic acid, Him = imidazole), which has been hydrothermally prepared and characterized by single-crystal X-ray diffraction, IR, ICP, XRPD, TGA, DSC, and element analysis. The overall architecture is constructed from alternate Co(II) and Cd layers arranged in ABAB mode, and affords a three-dimensional (3D) 4,6-conneccted (44 · 62)(48 · 66 · 8) topological network. Furthermore, magnetic property of 1 has also been studied in the temperature range of 5–300 K.
