【Abstract】 A complex [Ba(DB30C10)(H2O)][Bi2Cl8] has been grown in a gel reaction and characterized by elemental analysis, differential thermal and thermogravimetric analysis as well as infrared spectra. The molecular and crystal structure of the complex has been determined by X-ray diffraction.The structure of the ctystal was solved by Patterson method and Fourier synthesis, an a then it was refined by full matrix least squares method to final discrepancy factors R=0. 080. The crystal belongs to triclinic space group Plwith cell parameters:α= 11. 342(2), b=11. 812(2),c=16. 791(2),A ,α= 106. 49(l)0,β=95. 41(1)0,γ=94. 07(l)0,Z=2,Dc=2. 014g·cm-3.The result of structural determination indicates that the barium ion was located in the cavity of the crown ether and coordinated with the crown ether and a molecular water to form a complex cation while each bismuth (Ⅲ) ion was coordinated with six chlorids and forms an infinitely anionic chian {[Bi2(μ-Cl)2Cl4(μ-Cl)4/2]2-}n through bridging chlorid atoms.更多还原
