Polyunsaturated conjugated thiocarbonyl compounds (thioxocarotenoids) occur as monomers or react instantaneously to give polyene substituted trithiacyclohexanes and 2 H -thiopyrans.

We studied the elastic properties of γ′-Fe 4 N experimentally and theoretically, as the difference between calculated and measured literature data is up to 31%. A phase-pure γ′-Fe 4 N thin film and a bulk-like sample were synthesized using a re

Prior investigations of the ternary nitride series Ga 1– x Fe 3+ x N (0≤ x ≤1) have indicated a transition from ferromagnetic γ ′-Fe 4 N to antiferromagnetic “GaFe 3 N”. The ternary nitride “GaFe 3 N” has been magnetically and spectr

The recently published synthesis of the presumably daltonide phase InFe3N has been re-investigated. A two-step ammonolysis reaction gives access to the phase-pure berthollide InxFe4–xN (0 ≤ x ≤ 0.8), which adopts a perovskite-like structure in

We have explored the bulk modulus and the thermal expansion of PdFe3N (space group \(Pm\overline 3 m\)) using ab initio phonon dynamics within the quasiharmonic approximation in the temperature range from 50 to 1000 K. PdFe3N possesses a linear therm

First-principles, density-functional studies of several intermetallic borides of the general type M2M′Ru5−nRhnB2 (n=0–5; M=Sc, Ti, Nb; M′=Fe, Co) show that the variation in saturation magnetic moment with valence-electron count follows a Slat

The recently published two-step ammonolysis was adapted to the first synthesis of GaFe3N as a pure phase and AlFe3N with a very high phase purity. Similar to archetypal γ′-Fe4N (a = 3.7900(6) A), the ternary nitride GaFe3N adopts a perovskite-like

The title compound is characterized by prompt γ-ray activation analysis, 57Fe Moessbauer spectroscopy, and magnetic measurements in order to explore the weakening of the ferromagnetic interactions caused by the gradual incorporation of Ga into γ′

The title compounds are prepared by sintering mixtures of In2O3 and Fe2O3 at 600 °C for 5 h followed by ammonolysis with a 1:1 NH3:H2 mixture at 500 °C for 3 h.

The thermodynamic stability of GaFe3N (space group Pmm) is investigated by DFT calculations and the Vegard-like behavior of the compound discussed earlier is resolved using Mo Kα1 XRD.
