Abstract:Reaction of 1,4-bis(imidazol-1-ylmethyl)benzene (bix), 2,6-naphthalenedisulfonic acid (nds) with CdCl2 under hydrothermal condition, yielded a new three-dimensional Cd(II) coordination polymer [Cd(bix)(nds)]n, which was further structurally determined by X-ray single crystal diffraction. The result indicates that the compound exhibits centro-symmetrical in which the cadmium ion is located at the symmetry center. Each Cd(II) ion is six-coordinated with a distorted octahedral coordination geometry. The adjacent Cd(II) ions are connected by bix molecules, giving a one-dimensional chain, and the neighboring chains are further linked by sulfonic ions, resulting in two-dimensional sheet structure. In addition, the sheets are further bridged by the other sulfonic ions, generating infinite 3D network framework architecture.
