Chromium(II) bromide is the inorganic compound with the chemical formula CrBr 2.Like many metal dihalides, CrBr 2 adopts the "cadmium iodide structure" motif, i.e., it features sheets of octahedral Cr(II) centers interconnected by bridging bromide ligands.
Chromium compounds are compounds containing the element chromium (Cr). Chromium is a member of group 6 of the transition metals . The +3 and +6 states occur most commonly within chromium compounds, followed by +2; charges of +1, +4 and +5 for chromium are rare, but do nevertheless occasionally exist.
corundum (Al 2 O 3) aluminium oxide hydroxides diaspore (α-AlO(OH)) boehmite or böhmite (γ-AlO(OH)) akdalaite (5Al 2 O 3 ·H 2 O) (once believed to be 4Al 2 O 3 ·H 2 O), also called tohdite; aluminium hydroxides. gibbsite (often designated as γ-Al(OH) 3, but sometimes as α-Al(OH) 3, [4] sometimes called hydrargillite or hydrargyllite)
The only stable chalcogenides under normal conditions are aluminium sulfide (Al 2 S 3), selenide (Al 2 Se 3), and telluride (Al 2 Te 3). All three are prepared by direct reaction of their elements at about 1,000 °C (1,832 °F) and quickly hydrolyse completely in water to yield aluminium hydroxide and the respective hydrogen chalcogenide .
4 AlBr 3 + 3 CCl 4 → 4 AlCl 3 + 3 CBr 4. and with phosgene yields carbonyl bromide and aluminium chlorobromide: [citation needed] AlBr 3 + COCl 2 → COBr 2 + AlCl 2 Br. Al 2 Br 6 is used as a catalyst for the Friedel-Crafts alkylation reaction. [3] Related Lewis acid-promoted reactions include as epoxide ring openings and decomplexation of ...
Analogous to the behavior of related chromium(III) halides, the tribromide dissolves in water to give CrBr 3 (H 2 O) 3 only upon the addition of catalytic amounts of a reducing agent, which generates CrBr 2. [1] The reducing agent generates chromous bromide on the surface of the solid, which dissolves and re-oxidizes to Cr(III). [citation needed]
