摘要

Hydrothermal reactions of cadmium(II) salt with m-phosphonophenylsulfonic acid (H3L) and 1,10-phenanthroline (phen) or 4,4'-bipyridine (bipy) led to three novel cadmium(II) phosphonatephenylsulfonates, namely, [Cd-4(L)(2)(phen)(6)(Cl)(2)(H2O)(2)]center dot 14H(2)O (1), [Cd-6(L)(4)(phen)(8)]center dot 14H(2)O (2), and [Cd-3(L)(2)(bipy)(3)(H2O)(6)]center dot 4H(2)O (3). Compound 1 contains a tetranuclear cadmium(II) cluster in which four cadmium(II) ions are bridged by two tetradentate phosphonate groups. Compound 2 features a hexanuclear cadmium(II) cage in which six cadmium(II) ions are bridged by one tetradentate and three pentadentate phosphonate groups. The structure of compound 3 features a novel 3D network based on 1D chains of [Cd-3(L)(2)] cross-linked by 4,4'-bipy ligands; its topological structure is similar to that of CdSO4. Compounds 1-3 exhibit broad blue fluorescence emission bands at 408, 410, and 396 nm, respectively.
