Network crewn ether polymer with pendant sulfide side ohain in the networkstructure units has been synthesized via ring- opening copolymerization of β-ethylthioethyl glycidyl ether and diethylene glycol bisglycidyl ether. A kind of active catalyst suitable for this reaction was suggested. The title polymer was found tobe a good ligand for platinous chloride, and the platinous complex could catalyze thehydrosilylation of olefins with triethoxysilane efficiently. 展开更多

The crystal structure of crown ether-hydrogen bonded complex,[La(NO3)3 (12-crown-4) ( H2O)] (12-crown-4) has been determined by X-ray method. The title complex C16H34LaN3O18 (Mr=695. 5) crystallized in orthorhombic Pnma with a=23. 495(8), b=13. 603(5),c=8. 474(3); V=2706(1); Z=4 ; Dc=1. 71 g/cm3; F(000)=1408, μ=17. 0 cm-1 (MOKα). The final R=0. 052 and Rw= 0. 054(unit weight) for 1367 observed reflections. The La( Ⅲ) ion is 11-coordinated by three nitrale anions, four oxygen atoms from a crown ligand and one O atom of a water molecule. The other crown molecule is hydrogen bonded wilh the coordinated water molecule. The imposed mirror plane in the structure made both crown ligands and one of nitrate groups severely disordered. 展开更多

The title complex [Na (DB_18C_6) (H_2O)_2]_2Mo_6O_19·3DMF · 2CH_3OH (Ⅰ) , a new type of crown hexamolybdate supermolecule, has been synthesized. Its crystal structure has been determined by X-ray diffraction analysis. The crystal C_49H_32 Mo_6N_2Na_2O_40 is tetragonal, space group P4/mbm, a= 17.108(2), c= 28. 285 (6) A ,V=8279(2) A ̄ 3, Z=4 , M_r= 1960. 8 , D_x=1. 573 g/cm ̄3 , P=9. 51cm ̄(-1). F(000)=3936. The final agreement factors R=0. 058 and R_w= 0. 062 for 1777 independent reflections with F>4σ(F). In contrast to what we have reported about [Na(DB_18C_6)(CH_3OH)]_2Mo_6O_19(Ⅱ) where the whole complex was linked together, the cation [Na (DB_18C_6 ) (H_2O)_2] ̄ + , that has crystallographic D_2h symmetry, combines with the anion with the symmetry O_h by electronic interaction. 展开更多
