Nd08Sr02NiO2

Nd0.8Sr0.2NiO2 is a chemical compound belonging to the family of nickelate oxides. It has the chemical formula Nd(1-x)SrxNiO2 where x = 0.2. This material is a member of the Ruddlesden-Popper series and has garnered interest in materials science research due to its potential electronic and magnetic properties. The structure typically features layers of nickel-oxygen polyhedra separated by layers containing neodymium and strontium.

The synthesis of Nd0.8Sr0.2NiO2 often involves solid-state reactions at high temperatures. Precise control over the stoichiometry of neodymium and strontium is crucial for achieving the desired properties. Research into this compound has explored its electrical conductivity and magnetic ordering. The presence of strontium, a lower valence cation than neodymium, introduces holes into the nickelate lattice, influencing the electronic state of the nickel ions and consequently the material's behavior.

Studies have investigated the oxidation state of nickel in Nd0.8Sr0.2NiO2, which is generally considered to be close to Ni2+. The interplay between the crystal structure, the electronic configuration of nickel, and the doping concentration of strontium dictates the emergent phenomena observed in this material. Potential applications are being explored in areas such as catalysis and thermoelectric devices, though these remain areas of active scientific investigation.
