diiodide การใช้

• Transition metal dichalcogenides typically adopt either cadmium diiodide or molybdenum disulfide structures.
• Of the dihalides, difluoride is not known, dichloride is brown, dibromide is black, and diiodide is blue.
• The lower oxidation states are stabilized by the larger halogens, so that the trichloride, tribromide, triiodide, and even diiodide are known.
• Lead forms dihalides and tetrahalides with fluorine and chlorine, and forms a tetrabromide and a lead diiodide, although the tetrabromide and tetraiodide of lead are unstable.
• Other dihalides are received upon heating lead ( II ) salts with the halides of other metals; lead dihalides precipitate to give white orthorhombic crystals ( diiodide form yellow hexagonal crystals ).
• "' Americium ( II ) iodide "'or "'americium diiodide "'is the chemical compound composed of americium and iodine with the formula AmI 2.
• The first organotin compound was diethyltin diiodide ( ( C 2 H 5 ) 2 SnI 2 ), discovered by Edward Frankland in 1849 . The area grew rapidly in the 1900s, especially after the discovery of the Grignard reagents, which are useful for producing Sn-C bonds.
• For example, compressing the usual monoclinic samarium diiodide and releasing the pressure results in a PbCl 2-type orthorhombic structure ( density 5.90 g / cm 3 ), and similar treatment results in a new phase of samarium triiodide ( density 5.97 g / cm 3 ).
• Californium ( III ) chloride ( CfCl 3 ) is an emerald green compound with a hexagonal structure that can be prepared by reacting Cf 2 O 3 with hydrochloric acid at 500 癈 . CfCl 3 is then used as a feeder stock to form the yellow-orange triiodide CfI 3, which in turn can be reduced to the lavender-violet diiodide CfI 2.
