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 given… Expand
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 orthorhombic… Expand
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 modification… Expand
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). The… Expand
