| Abstract: | An unprecedented 1D zigzag chain alkaline earth metal derivative, {[Ba(DMF)3 (H2O)2][Ba(DMF)4]2(P2W18O62)}n, (DMF=N, N-dimethyl formamide) containing Dawson hetero- polyanion 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. |
