Iodide Nitride
An iodide nitride is a mixed anion compound containing both iodide (Iā) and nitride ions (N3ā). Another name is metalloiodonitrides. They are a subclass of halide nitrides or pnictide halides. Some different kinds include ionic alkali or alkaline earth salts, small clusters where metal atoms surround a nitrogen atom, layered group 4 element 2-dimensional structures (which could be exfoliated to a monolayer), and transition metal nitrido complexes counter-balanced with iodide ions. There is also a family with rare earth elements and nitrogen and sulfur in a cluster. Related mixed-anion compounds include halogen variations: nitride fluoride, nitride chloride, and nitride bromide, and pnictogen variations phosphide iodide, arsenide iodide and antimonide iodides. Production Nitride iodides may be produced by heating metal nitrides with metal iodides. The ammonolysis process heats a metal iodide with ammonia. A related method heats a metal or metal hydride with ammonium iodide. T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mixed Anion Compound
Mixed anion compounds, heteroanionic materials or mixed anion materials are chemical compounds containing cations and more than one kind of anion. The compounds contain a single phase, rather than just a mixture. Use in materials science By having more than one anion, many more compounds can be made, and properties tuned to desirable values. In terms of optics, properties include laser damage threshold, refractive index, birefringence, absorption particularly in the ultraviolet or near infrared, non-linearity. Mechanical properties can include ability to grow a large crystal, ability to form a thin layer, strength, or brittleness. Thermal properties can include melting point, thermal stability, phase transition temperatures, Thermal expansion coefficient. For electrical properties, electric conductivity, band gap, superconducting transition temperature piezoelectricity, pyroelectricity, ferromagnetism, dielectric constant, charge-density wave transition can be adjus ...
