Article Synopsis
- A neutral iron(III) complex hydrate based on pyruvic acid thiosemicarbazone was synthesized and analyzed using various methods like FT-IR spectroscopy and X-ray diffraction, with its structure being reported for the first time.
- The structure features an octahedron geometry around the Fe(III) ion formed by two ligands, resulting in unique interactions, including π-π interactions and hydrogen bonding.
- Notably, the magnetic properties show a spin-crossover phenomenon at temperatures between 300-363 K, revealing weak antiferromagnetic exchange interactions between iron(III) centers, confirmed by theoretical calculations.
Article Synopsis
- The article discusses the creation of hybrid composite films by combining graphene oxide (GO) nanosheets with a spin-crossover complex and an organic cation, resulting in a new material called GO-1.
- The hybrid material's properties were thoroughly analyzed using various advanced techniques, including microscopy and spectroscopy, to understand its structure and composition.
- Results indicate that the GO nanosheets significantly affect the spin transition properties and magnetic behavior of the composite, highlighting the importance of the organic cation in the formation process.
Potassium manganese fluoride phosphate, KMnPOF, has been obtained through mild hydrothermal synthesis and characterized by scanning electron microscopy, microprobe analysis and X-ray diffraction. The compound possesses an orthorhombic symmetry and chiral space group 222 with = 4.7884(2), = 9.
