Curium(III) Iodide
Curium(III) iodide is the chemical compound with the formula . Since all isotopes of curium are only artificially produced, the compound has no natural occurrence. Synthesis Elemental curium and iodine can be reacted to synthesize curium(III) iodide. :: Also by the reaction of curium(III) chloride with ammonium iodide: :: Physical properties Curium(III) iodide is a colorless ionic compound consisting of Cm3+ and I− ions. It forms white crystals the hexagonal crystal system in the space group ''R3'' (space group no. 148) with the lattice parameters a = 744 pm and c = 2040 pm with six units per unit cell. Its crystal structure is isotypic with that of bismuth(III) iodide Bismuth(III) iodide is the inorganic compound with the formula Bi I3. This gray-black salt is the product of the reaction of bismuth and iodine, which once was of interest in qualitative inorganic analysis. Bismuth(III) iodide adopts a distin ....

Curium(III) Chloride
Curium(III) chloride is the chemical compound with the formula CmCl3. Structure Curium(III) chloride has a 9 coordinate tricapped trigonal prismatic geometry. Synthesis Curium(III) chloride can be obtained from the reaction of hydrogen chloride gas with curium dioxide, curium(III) oxide, or curium(III) oxychloride at a temperature of 400-600 °C: : It can also be obtained from the dissolution of metallic curium in dilute hydrochloric acid: :2Cm 6HCl -> atop\ce2CmCl3 3H2 This method is complicated by the ongoing processes of hydrolysis and hydration of the resulting compound in an aqueous solution, making it problematic to obtain a pure product. It can be obtained from the reaction of curium nitride with cadmium chloride Cadmium chloride is a white crystalline compound of cadmium and chloride, with the formula CdCl2. This salt is a hygroscopic solid that is highly soluble in water and slightly soluble in alcohol. The crystal structure of cadmium chloride (descr ...

Ammonium Iodide
Ammonium iodide is the inorganic compound with the formula NH4I. A white solid. It is an ionic compound, although impure samples appear yellow. This salt consists of ammonium cation and an iodide anion.Holleman, A. F.; Wiberg, E. ''Inorganic Chemistry'' Academic Press: San Diego, 2001. . It can be prepared by the action of hydroiodic acid on ammonia. It is easily soluble in water, from which it crystallizes in cubes. It is also soluble in ethanol. Ammonium iodide in aqueous solutions are observed as acidic and display elevated vapor pressures at high temperatures Preparation Ammonium iodide can be made in lab by treating ammonia with hydroiodic acid: : NH3 + HI → NH4I Uses Ammonium iodide is used as dietary supplement to treat iodine deficiency Iodine deficiency is a lack of the trace element iodine, an essential nutrient in the diet. It may result in metabolic problems such as goiter, sometimes as an endemic goiter as well as congenital iodine deficiency syndrome ...
