摘要
An unprecedented 1D zigzag chain alkaline earth metal derivative, {[Ba(DMF)(3) (H2O)(2)][Ba(DW)(4)](2)(P2W18O62)}(n), (DMF=N, N-dimethyl formamide) containing Dawson heteropolyanion has been successfully synthesized and characterized by X-ray crystallography. Two barium cations bridged by three DMF ligands in parallel combination with the Dawson-type heteropolyanion [P2W18O62](6-) and then the resulting subunits {[Ba(DMF)(4)](2)(P2W18O62)}(2+) are alternately linked together via another [Ba(DMF)(3)(H2O)(2)](2+) ions, constructing a 1D zigzag chain architecture.
