Iridium(III) bromide is a dark reddish-brown solid that is insoluble soluble in water, acids, and alkalis and decomposes to iridium(II) bromide on heating. [1] It crystallizes in a highly disordered layered structure of aluminum(III) chloride or chromium(III) chloride type, where the monoclinic unit cell contains four formula units.

Iodine monobromide is an interhalogen compound with the formula IBr. It is a dark red solid that melts near room temperature. [1] Like iodine monochloride, IBr is used in some types of iodometry. It serves as a source of I +. Its Lewis acid properties are compared with those of ICl and I 2 in the ECW model.
Indium(III) bromide, (indium tribromide), InBr 3, is a chemical compound of indium and bromine. It is a Lewis acid and has been used in organic synthesis. [2]
Tribromide is the anion with the chemical formula Br 3 −, or salts containing it: . Tetrabutylammonium tribromide; Tetrabromophosphonium tribromide; Pyridinium perbromide; Sodium and potassium tribromides can be prepared by reacting NaBr or KBr with aqueous bromine.
Iridium tetrabromide is a binary inorganic chemical compound of iridium and bromine with the chemical formula IrBr 4. [ 1 ] [ 2 ] [ 3 ] This is a salt of iridium metal and hydrobromic acid . Synthesis
In this compound, each of the iridium atoms is bonded to the other three, forming a tetrahedral cluster. The discovery of Vaska's complex (IrCl(CO)[P(C 6 H 5) 3] 2) opened the door for oxidative addition reactions, a process fundamental to useful reactions. For example, Crabtree's catalyst, a homogeneous catalyst for hydrogenation reactions.
