Synthesis and Structure of a Cerium Coordination Polymer Templated by Double-Keggin-anion
porous coordination polymer, {[Ce(dpdo)4(H2O)3](Pmo12O4)(dpdo)0.5(H2O)4}n1 (dpdo = 4,4"-bipyridine-N,N'-dioxide), templated by double-Keggin-type polyanions was synthesized and structurally characterized. The crystal structure was determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group Pi with a = 13.368(4), b = 16.503(4), c =18.506(5) A, α = 88.831(5), β = 82.095(5), y = 83.578(5)°, V = 4018.6(18) A3, Z = 2, C45H50N9O56CeMo12P, Mr = 2935.31, Dc = 2.426 g/m3,μ = 2.491 mm-1, F(000) = 2816, the final R = 0.0603 and wR = 0.1611 for 11977 observed reflections with I> 2σ(I). Compound 1 exhibits a 3D non-interwoven framework with large cavities housing centrosymmetrically related shoulder-by-shoulder double-Keggin anions as guests.
