Untersuchungen zur Reaktivität in den Systemen A/Cu/M/O (A = Na-Cs und M = Co, Ni, Cu, Ag); Synthese und Kristallstrukturen von K3Cu5O4 und Cs3Cu5O4

CsCu 3 O 2 was prepared via the azide route. Stoichiometric mixtures of the precursors (CsN 3 , Cu 2 O and CuO) were heated in a special regime up to 450°C and annealed at this temperature for 50 h in silver crucibles. Single crystals have been grown by subsequent annealing of as prepared powders at 450°C for 2000 h in silver crucibles, which were sealed in glass ampoules under dried Ar. According to the X-ray analysis of the crystal structure (P3m1, Alkalioxocuprates(I) are known to form three families of general compositions A 3 Cu 5 O 4 (A ϭ K [1, 2], Rb [3], Cs [2, 3]; K 2 RbCu 5 O 4 , KRb 2 Cu 5 O 4 [3]), ACuO (A ϭ Li [4Ϫ6], Na [6, 7], K [5, 6], Rb [6, 7] and Cs [8]), and A 3 CuO 2 (A ϭ K [9], Rb [10] and Na 2 KCuO 2 [11]). Their crystal structures are all dominated by the presence of linear units CuO 2 , in different connectivities, depending on the respective Cu/O-ratio. In spite of the fact that argentates(I) of the type AAg 3 O 2 (A ϭ Li [12], Na [13]) have been shown to exist, no copper analogue has been reported, so far. Here we present the synthesis and structure determination of CsCu 3 O 2 , a first representative.

The aim of this research report is to give an introduction to a specific solid state reaction applied in the field of alkali metal rich transition metal compounds. The approach is an explorative investigation of the oxidation of transition metals with CdO in the presence of alkali metal oxides and / or compounds with complex anions such as Na2SO4. Thereby, a range of unusual compounds have been obtained and structurally characterized. In particular, low valences and uncommon coordination numbers (C.N.) of the late 3d transition metals, as well as interesting varieties in the anionic part of the structures are accessible. The presented examples were selected mainly in order of their inherent aspects concerning the reactivity, structural features or electronic structures.
