Construction of six non-covalent-bonded supramolecules from reactions of cadmium(II), and zinc(II) with 3,5-dimethylpyrazole and carboxylate ligands

Six complexes from 3,5-dimethylpyrazole and carboxylates were prepared and characterized by EA, IR spectra, TG, and single crystal XRD analysis. These complexes display mononuclear to trinuclear structures with tetrahedral geometry for zinc cation and octahedral coordination for cadmium cation. The extensive nonbonding interactions in 1-6 are responsible for the formation of 3D network, 2D sheet, and 3D layer network structures.
