Abstract

Two organic–inorganic hybrid polyoxotungstogermanates, HK7(H2O)6(C6H16N2)6-[Fe(C6H14N2)Dy(H2O)2Fe2(B-α-GeW9O34)(GeW7O29)]2·14H2O (1) and (Hphen)2[Fe(phen)3]2[Dy(phen)Fe(B-α-GeW9O34)]2 (2) (C6H14N2 = trans-1,2-cyclohexanediamine, phen = 1,10-phenanthroline), containing organic ligand chelated Fe–Dy heterometallic clusters have been successfully synthesized under hydrothermal conditions. Compound 1 contains a cable-like structural fragment which consists of a centrosymmetric “S”-shaped K7O14 cluster and a centrosymmetric “S”-shaped organic ligand chelated Fe–Dy heterometallic cluster substituted tungstogermanate, {[Fe(C6H14N2)Dy(H2O)2Fe2(B-α-GeW9O34)(GeW7O29)]2}20−. Compound 2 possesses a sandwich structure which contains two trilacunary [B-α-GeW9O34]10− units and one {(phen)DyFeO6}2 cluster in the middle layer. Both compounds have magnetic properties, with compound 1 having frequency dependent magnetic properties.
