A Novel Organosulfonate Cadmium(II) Complex with Graphite-like 2D Layer Linked by Hydrogen Bonds
A novel mixed‐ligand complex, [Cd(im)6][Cd(im)3(H2O)3]2(ans)6·8H2O (1), was obtained from the reaction ofCd(OAc)2·2H2O, imidazole (im) and sodium 4‐aminonaphthalene‐1‐sulfonate tetrahydrate (Na‐ans) in a mixed solvent at 25 °C. The complex was characterized by elemental analysis, IR spectroscopy, an...

Summary: | A novel mixed‐ligand complex, [Cd(im)6][Cd(im)3(H2O)3]2(ans)6·8H2O (1), was obtained from the reaction ofCd(OAc)2·2H2O, imidazole (im) and sodium 4‐aminonaphthalene‐1‐sulfonate tetrahydrate (Na‐ans) in a mixed solvent at 25 °C. The complex was characterized by elemental analysis, IR spectroscopy, and X‐ray single crystal diffraction. There are two kinds of cations constructed by CdII atoms with a octahedral coordination arrangement in 1. The CdII atom is bonded by six nitrogen atoms from six im ligands in the first cation, and the second central CdII atom is bonded by three nitrogen atoms of im molecules and three oxygen atoms belonging to water molecules. The ans anion acts as a counterion to balance the charge, and the adjacent anions are reversed but non‐parallel interlinked by N–H···O(S) hydrogen bonds into graphite‐like 2D sheet viewed from the c axis. The anionic channels along the [110] direction are filled with the cations, and the two kinds of cations are alternatingly arranged in the channels. The hydrogen‐bonding interactions together with the ionic bonds stabilize the crystal structure. The thermostability of the complex was investigated by TG and DSC. |
