Complex oxides with perovskite-like crystalstructures are of great interest due to their unique properties: high-temperature superconductivity, colossal magnetoresistance [ 1 , 2 ], photocatalytic activity in

anatase crystalstructure is more favorable than rutile as it is more active with band gap energy of 3.2 eV than rutile (3.0 eV) [ 29 , 30 ].
Consequently, the reason for the increase in the photocatalytic activity of film B should be ascribed to

Molecular and crystal structure of diaqua-sulphato(pyridoxal semicarbazone-ONO)iron(II) and dichloroaqua(pyridoxal semicarbazone-ONO)iron(III)
complexes with tridentate ONO pyridoxal semicarbazone ligand, PLSC, of formula [FeII(PLSC)(H2O)2SO4] and [FeIII(PLSC)(H2O)Cl2]Cl is reported. Thermal decomposition of the compounds was followed in argon and air gas carriers. The dequation mechanism
is discussed in the view of the crystal structure, emphasizing the complexity of the related parameters and processes.

The crystal structure, thermal properties and growth rates of spherulites of the Tussah silk fibroin, produced upon drying
of the silk taken directly from the lumen which is essentially a poly(L-alanine)polypeptide, are investigated. Depending on casting conditions, spherulites with either αhelical chain conformation
or β parallel sheet structure are produced. The growth rates display a strong positive temperature coefficient, with an apparent
transition, which however cannot be related with the formation of two different crystal structures at this stage.

The effect of the mechanical treatment of UO2(CH3COO)2·2H2O in a planetary ball mill in air or as a suspension in toluene or benzene on its crystal structure and coordination mode
has been studied. No significant changes in the crystal structure are observed. IR-spectroscopy results suggest that in the
part of the mechanoactivated material the bidentate bonding of the CH3COO− is transformed in monodentate one. The newformed species is soluble in non-polar solvents.
