      Linking orthopalladated ferrocenylene units with parabanato(2–) ligands results in enantiospecific assembly of a homochiral, hexapalladium complex, as shown by 1H NMR spectroscopy and single-crystal X-ray analysis. The six homochiral ferrocenylene-palladium groups (R,R,R,R,R,R or S,S,S,S,S,S) give rise to a tapering, twisted, trigonal-prismatic structure which shows overall helical chirality.

      Article first published online: 3 FEB 2009 | DOI: 10.1002/ejic.200801176

      Thumbnail image of graphical abstract

      Although a seemingly unsuitable choice (C=N and C–O vs. C–N and C=O bond, seven- vs. five-membered chelate, Si-out-of-chelate-plane position etc.), Schiff base type N-(2-carbamidophenyl)imines adopt a fac-O,N,O′ coordination mode in six-coordinate silicon complexes of the type SiL2.

    13. Electron-Doped Double Perovskites

      The Magnetotransport Properties and a Neutron Diffraction Study of Sr2–xNdxFeMoO6 Double Perovskites (pages 1103–1109)

      María Retuerto, María Jesús Martínez-Lope, Mar García-Hernández and José Antonio Alonso

      Article first published online: 3 FEB 2009 | DOI: 10.1002/ejic.200800958

      Thumbnail image of graphical abstract

      Injection of Nd at the Sr sublattice of Sr2–xNdxFeMoO6 double perovskites produces an effective electron doping localized preferentially at Mo sites and promotes an anti-site disorder between Fe and Mo, which creates antiferromagnetic clusters that decrease the saturation magnetization. The abnormal magnetoresistance behaviour observed could be due to the introduction of a magnetic rare earth.

Uniform and almost stoichiometric Ga2O3 thin films can be formed from 2 as a precursor in a horizontal cold-wall reactor.
