About Formamidinium Iodide

Formamidinium Iodide (FAI) is an organoiodine compound that serves as a precursor material for the synthesis of formamidinium-lead-iodide (FAPbI3)-based perovskites, which are under investigation as highly efficient solar cell materials. American Elements supplies organometallic compounds in most volumes including bulk quantities and also can produce materials to customer specifications. Most materials can be produced in high and ultra high purity forms (99%, 99.9%, 99.99%, 99.999%, and higher) and to many standard grades when applicable including Mil Spec (military grade), ACS, Reagent and Technical Grades, Pharmaceutical Grades, Optical, Semiconductor, and Electronics Grades.

The number of electrons in each of Iodine's shells is 2, 8, 18, 18, 7 and its electron configuration is [Kr] 4d10 5s2 5p5. The iodine atom has a radius of 140 pm and a Van der Waals radius of 198 pm. In its elemental form, iodine has a lustrous metallic gray appearance as a solid and a violet appearance as a gas or liquid solution. Elemental IodineIodine forms compounds with many elements, but is less active than the other halogens. It dissolves readily in chloroform, carbon tetrachloride, or carbon disulfide. Iodine compounds are important in organic chemistry and very useful in the field of medicine. Iodine was discovered and first isolated by Bernard Courtois in 1811. The name Iodine is derived from the Greek word "iodes" meaning violet.
