Abstract
The reactions of BaCl2·2H2O with NaHLa and K3Lb (H2La=4-hydroxybenzenesulfonic acid, H3Lb=4-hydroxy-5-nitro-1,3-benzenedisulfonic acid) gave two pillared layered coordination polymers: Ba(HLa)(Cl) 1 and KBaLb(H2O)32, respectively. The crystal structures were determined by X-ray diffraction method and refined by full-matrix least-squares methods to R=0.0509 and wR=0.1216 using 1455 reflections with I>2Ï(I) for 1; and R=0.0288 and wR=0.0727 using 2661 reflections with I>2Ï(I) for 2. The interesting feature of compound 1 is the coordination actions of chloride anions, which help to form the polymeric layers by bridging barium cations. In compound 2 the Lb3â anion acts as an unusual dodecadente ligand to form a coordination polymer with pillared layered structure.
