The crystal structures of six A2M3+M5+O6 ordered perovskites as determined from X-ray and neutron powder diffraction data are reported here. These samples show a high degree of pseudosymmetry that complicates the interpretation of the powder diffraction data. Correct space-group assignments were made through the systematic analysis of the supercell reflections, splitting of the fundamental perovskite peaks and crystal chemical considerations.
metal-organic compounds
1,12-Diferrocenyldodecane, [Fe2(C5H5)2(C22H32)], was synthesized from ferrocene and 1,12-dodecanedioyl chloride, followed by Clemmensen reduction. The single-crystal structure was determined at 100 K by X-ray diffraction and the spectroscopic and cyclic voltammetric data of 1,12-diferrocenyldodecane and its precursor are reported.

The software program SPuDS has been developed to calculate the crystal structures of distorted perovskites. Calculated structures are compared with known crystal structures in order to verify the accuracy of this approach. Further calculations are presented to demonstrate the possible application of this program for synthesizing new materials.
research papers
Cooperative Jahn-Teller distortions and their interplay with octahedral tilting and cation ordering have been examined systematically in AMX3 perovskites containing a Jahn-Teller ion on the octahedral site, as well as in quaternary A2MM'X6 perovskites containing a Jahn-Teller ion on one-half of the octahedral sites.
research papers
The capabilities of the program SPuDS have been extended to predict crystal structures of A2MM′X6 ordered double perovskites. Its accuracy and potential applications are discussed.
