Description
Summary:Coordination polymers of cadmium(II) with the di(pyrazol-1-yl)alkane derivatives, bis(3,5-dimethylpyrazol-1-yl)methane-4,4′-dicarboxylic acid (H 2 L 1 ) and 1,3-bis(pyrazol-1-yl)propane-4,4′-dicarboxylic acid (H 2 L 2 ), are synthesized. The crystal structures of the products are determined by X-ray diffraction (CIF files CCDC nos. 2172853 ( I ) and 2172854 ( II )). The Cd 2+ ions and dicarboxylic acid with one methylene group between the pyrazole cycles form a three-dimensional coordination polymer with a single mutual intergrowing of coordination networks, whereas three methylene groups result in the formation of a two-dimensional coordination polymer, the layers of which are linked by hydrogen bonds involving water molecules in the coordination sphere of the Cd 2+ ions. The luminescence spectra of the synthesized coordination polymers exhibit two bands: with the local intraligand excitation and with the metal–ligand charge transfer.
