Calcium platinum(IV) oxide has been synthesized from a flux and structurally characterized by single-crystal X-ray diffraction. It is isostructural with Sr4PtO6 [Randall & Katz (1959). Acta Cryst. 12, 519-521] and Ba4PtO6 [Wilkinson & Cheetham (1989). Acta Cryst. C45, 1672-1674].

The title bismuth-iodide compound, [Bi2I6(C12H8N2)2], has been synthesized solvothermally by reacting BiI3, Mn(CH3COO)2·4H2O, and 1,10-phenanthroline in an ethanol/water solvent mixture. The compound contains two bismuth centers that are each coordinated by a phenanthroline ligand and two terminal iodide ligands, and the bismuth centers are bridged via two additional iodide ligands to form a molecular dimer. The asymmetric unit of the compound consists of one half of a single dimer molecule located on a crystallographic inversion center.


Description Of Ba1 + XNiXRh1 - XO3 With X = 0.1170 (5) In Superspace: Modulated Composite Versus Modulated-Layer Structure, A. Schönleber, F. Zúñiga, J. Perez-Mato, J. Darriet, Hans Conrad Zur Loye Nov 2011

Description Of Ba1 + XNiXRh1 - XO3 With X = 0.1170 (5) In Superspace: Modulated Composite Versus Modulated-Layer Structure, A. Schönleber, F. Zúñiga, J. Perez-Mato, J. Darriet, Hans Conrad Zur Loye

The structure of the compound Ba1 + xNixRh1 - xO3 [x = 0.1170 (5)] has been analyzed at room temperature within the (3 + 1)-dimensional superspace approach using single-crystal X-ray diffraction data. Two different models are presented, the compound is refined as modulated composite as well as modulated-layer structure. In both models discontinuous atomic domains are applied to describe the structural modulations. While the first approach stresses the pseudo-one-dimensional constitution, the latter highlights the layered character of these structures.

InFeO3 is isostructural with the recently reported InMnO3. The structure of InFeO3 contains layers of In-O octahedra and Fe-O trigonal bipyramids. The trigonal bipyramids have ideal D34 symmetry. This unusual structure is unexpected within the context of known sesquioxide structures.
