In the context of investigating isostructural relationships between sulfates and monofluorophosphates, crystals of the double salts (NH4)2PO3F·NH4NO3 (AFP·AN) and (NH4)2XO4·3NH4NO3 (AX·3AN; X = Se, Cr) were grown from aqueous solutions and structurally ...

Synthesis and crystal structure of Ge(SO4)2
Abstract Colourless single crystals of Ge(SO4)2 were obtained as single phase products from the binary oxides GeO2 and SO3. The reaction was carried out in a silica glass ampule enclosed in an autoclave at 350 °C. Ge(SO4)2 forms a layer structure with corner‐linked GeO6 octahedra and SO4 tetrahedra.

Phase formation studies and crystal structure refinements in the MnII/TeIV/O/(H) system
Abstract Systematic phase formation studies in the system MnII/TeIV/O/‐(H) using either solid‐state reactions between stoichiometric MnO:TeO2 mixtures or hydrothermal reactions under basic conditions led to crystal growth of two polymorphs (α‐, γ‐) of MnTeO3, Mn6Te5O16, Mn15(TeO3)14(OH)2 and Mn3(TeO3)2(OH)2.

The Stacking Faulted Nature of the Narrow Gap Semiconductor Sc2Si2Te6
Abstract Crystals of Sc2Si2Te6 have been grown and its crystal, micro‐ and electronic structures were investigated. The layered character of the title compound exhibits stacking faults that impede a full structural characterization by single crystal X‐ray diffraction due to diffuse scattering.

APd2Zn3 (A=Ca, Sr, Eu) with a CaCu5 superstructure
Abstract The intermetallic phases APd2Zn3 (A=Ca, Sr, Eu) were synthesized from the elements in sealed niobium ampules in an induction furnace. The phase purity of the samples was checked by powder X‐ray diffraction (Guinier technique). The structures were refined from single crystal X‐ray diffractometer data: YNi2Al3 type (CaCu5 superstructure), P6/mmm,

By precipitation from aqueous HBr we obtained 12 new compounds of the ternary and quaternary systems RbBr/CuBr2, ABr/CuBr2, and ABr/RbBr/CuBr2 (A=organic cation). Their crystal structures were determined by single crystal measurements. The new compounds range from 0D to 3D structures with octahedral (4+2, 2+4) or tetrahedral surroundings of the Cu2 ...

13 structures based on Ni(II) and Co(II) metal centers and 1H,1′H‐4,4′‐bipyrazole linkers are discussed, with the linker being neutral in 11 of them. The role of the anion on framework dimensionality in those structures and correlations of the different structures are discussed.

Chalkogenide durch Reduktion ihrer Dioxide in ultra‐alkalischen Medien
Die unerwartete Reduktion von Selen(IV)‐ und Tellur(IV)‐Oxiden zu Chalkogeniden wurde unter ultraalkalischen Bedingungen durch die Verwendung von As2O3 als Reduktionsmittel ermöglicht. Durch Optimierung der Reaktionsbedingungen konnten innerhalb von zwei Tagen große Kristalle von K2Se3, K2Te3 und K2Se2Te gezüchtet werden.
