Binary and ternary carbides of alkali and alkaline-earth metals
Abstract The review surveys the preparation methods, crystallochemistry and physical properties (i.e. mainly spectroscopic properties) of binary and ternary carbides of Group I or Group II metals.Expand
Vacancy-Controlled Na+ Superion Conduction in Na11 Sn2 PS12.
This work presents the superionic conductor Na11 Sn2 PS12, which possesses a room temperature Na+ conductivity close to 4 mS cm-1, thus the highest value known to date for sulfide-based solids, and indicates that sodium electrolytes are about to equal the performance of their lithium counterparts.

Structural Phase Transition in Li2C2
Pure polycrystalline Li2C2 could be obtained by the reaction of lithium and graphite flakes in an arc-melting furnace. X-ray powder investigations on these samples confirm the crystal structure givenExpand
Structural phase transitions in CaC2.
It was shown that phase transition temperatures as well as the relative amounts of the various CaC2 modifications depend upon the size of the crystallites, the thermal treatment and the purity of the sample, as a comparison with technicalCaC2 confirmed. Expand
Structural Phase Transitions in Ag2Se (Naumannite)
Ag2Se (naumannite) was investigated by means of temperature dependent synchrotron powder diffraction and DTA. Upon heating in air the known 1st order phase transition from orthorhombicExpand
On the synthesis and crystal structure of BaC2
Abstract By the reaction of BaCO 3 with graphite in an arc melting furnace single crystals of BaC 2 could be synthesized. Structural investigations confirm the tetragonal structure (space group: I 4/Expand
Synthesis and Crystal Structure of SrC2
Abstract Polycrystalline SrC2 of high purity was prepared by the reaction of elemental strontium with graphite at temperatures of about 970 K. The known tetragonal room-temperature modificationExpand
Li3FeN2, a ternary nitride with ∞1[FeN4/23-]-chains: Crystal structure and magnetic properties
Abstract Li3FeN2 was prepared from the melt under nitrogen and the crystal structure was determined by single-crystal diffraction (Ibam; a = 487.2(1) pm, b = 964.1(2) pm, c = 479.2(1) pm, Z = 4). TheExpand
Metal-organic frameworks as hosts for photochromic guest molecules.
Several metal-organic framework compounds were loaded with azobenzene (AZB) and the influence of the host material on the switching behavior of the embedded AZB molecules was shown. Expand
