A novel mixed cadmium zirconium cesium oxalate with an open architecture has been synthesized from precipitation methods at room pressure. It crystallizes with an hexagonal symmetry, space group P3112 (no. 151), a=9.105(5)?, c=23.656(5)?, V=1698(1)?3 and Z=3. The structure displays a [CdZr(C2O4)4] 2- helicoidal framework built from CdO8 and ZrO 8 square-based antiprisms connected through bichelating oxalates, which generates channels along different directions. Cesium cations, hydronium ions and water molecules are located inside the voids of the anionic framework. They exhibit a dynamic disorder which has been further investigated by 1H and 133Cs solid-state NMR. Moreover a phase transition depending both upon ambient temperature and water vapor pressure was evidenced for the title compound. The thermal decomposition has been studied in situ by temperature-dependent X-ray diffraction and thermogravimetry. The final product is a mixture of cadmium oxide, zirconium oxide and cesium carbonate.

Novel methods of synthesizing heteroatom-containing chiral porphyrins and chiral metalloporphyrins and the novel chiral porphyrins and chiral metalloporphyrins themselves are disclosed. Metal complexes of the chiral porphyrins are prepared in high yields and shown to be active catalysts for highly enantioselective and diastereoselective cyclopropanation, aziridination, and epoxidation of alkenes under a practical one-pot protocol.

The preparation and crystal structure of the novel ternary oxides M3AuO (M=Cs, Rb, K) containting anionic gold is reported. Cs3AuO (a=7.830(1) A, c=7.060(1) A) crystallizes as an hexagonal, Rb3AuO (a=5.501(1) A), K3AuO (a=5.240(1) A) as a cubic anti perovskite. Concerning to the ionic description (M(1+))3Au(1-)O(2-) in Cs3AuO gold exists as an anion. In Rb3AuO and K3AuO the anionic character of gold decreases respectively. The analysis of bond length and molar volumes gives support to this view, as well as investigations of conductivity and magnetic properties do.
