    Notes: An all-alkoxide route to films and nano-phase powders of the La0.5Sr0.5CoO3 perovskite is described. To our knowledge, this is the first purely alkoxide-based route to (La1−xSrx)CoO3, and it yields phase-pure and elementally homogeneous perovskite at 700°C by heating at 2°C/min. At 700°C, a cubic unit cell was obtained with ac=3.853Å, and after further heating to 1000°C, a rhombohedral cell could be indexed: ar=5.417 Å, αr=59.94°. Ninety to 130 nm thick films of La0.5Sr0.5CoO3 were obtained by spin coating. The gel-to-oxide conversion was studied in some detail, using thermo-gravimetric analysis, differential scanning calorimetry, powder X-ray diffraction, IR spectroscopy, and transmission electron microscope equipped with an energy-dispersive X-ray spectrometer.

    Notes: The new tetranuclear alkoxide hexa-μ2-isopropoxy-1:2κ4O;1:3κ4O;1:4κ4O-hexaisopropoxy-2κ2O,3κ2O,4κ2O-trialuminium(III)neodymium(III), [Nd{Al(C3H7O)4}3], has a metal–oxygen NdAl3O12 core which consists of four metal atoms arranged in an approximately planar triangular geometry. The central Nd atom is six-coordinated by O atoms and the Al atoms are four-coordinated by O atoms.

    Notes: The preparation of LaNiO3, La4Ni3O10, La3Ni2O7-δ and La2NiO4 via La-methoxy-ethanolato-Ni(acac)2 precursor was investigated. From these precursors films, fibers and powders were prepared and heat treated to form LaNiO3 at temperatures as low as 750°C with a heating time of 4 h. The formation of La4Ni3O10 and La2NiO4 was complete at 1,000°C, for 4 h, while monophasic La3Ni2O7 required heating to 1,150°C, for 1 h. Pathways yielding various phases were also discussed briefly. The techniques used in this study are TGA, mass-spectroscopy, SEM-EDS, TEM-EDS, powder-XRD, and FT-IR spectroscopy.
