Two new coordination polymers with flexible alicyclic carboxylate and bipyridyl co-ligands bearing trinuclear [Ni3(COO)6] SBUs: Synthesis, crystal structures, and magnetic properties
文摘
Hydrothermal synthesis of two new coordination polymers of Ni(II) with flexible ligands. Investigation by elemental analysis, FT-IR spectra, TGA, PXRD, single-crystal X-ray diffraction. The structures feature trinuclear nickel SBUs connected via the bipyridyl spacers to form two-dimensional (4,4) grid layer. Magnetic studies indicate the ferromagnetic intra-complex magnetic interaction.
