Copper(II) fluoride loses fluorine as it melts. At 950°C it converts to cop-per(I) fluoride (cuprous fluoride), CuF ... [Pg.267]

Copper 11 halides are formed with chlorine, bromine and iodine, the chloride and bromide by reduction of the coppertll) halides with copper powder, and the iodide by reduction of coppertll) sulfate. CuSOj solulion with potassium iodide. The fluoride appears never to have been made, despite reports to the contrary. All are insoluble in H20. CoppertUl fluoride, CuF may be made from CuO and hydrofluoric acid at 400°C. coppertll) chloride. CuCl by dissolving the oxide or carbonate in HCI, and coppertll) bromide. CuBr from copper and bromine water coppertll) iodide. Cub, is unstable at room temperature with respect to decomposition intu Cul and iodine. The chloride and bromide are water-soluble, and ionic. The fluoride is only slightly water-soluble. Anhydrous copper(U) chloride. Cud , is monoclinic and its structure contains infinite-chain molecules formed by CuCLi groups that share opposite edges. CuBr. has a similar structure. [Pg.441]

Cuprous fluoride, CuF.—The fluoride has been prepared by the interaction of hydrogen fluoride and cuprous chloride, and also by the dissociation of cupric fluoride, both processes taking place at a high temperature.9 The product of the action of hydrogen-fluoride solution bn cuprous oxide10 appears to be impure copper only.11 The fluoride is a ruby-red solid. [Pg.261]

Coppers second oxidation state (+2) forms cupric compounds, also referred to as copper(II), which are more stable than copper(l) compounds. For example, copper in both oxidation states can combine with fluorine for copper(I) or cuprous fluoride, Cu" " + F CuF and for copper(ll) or cupric fluoride, Cu " " + 2F —> CuF. ... [Pg.111]

Copper(ii).—Halides. The complex [CuF(aq)] has been identified in copper(ii)-fluoride solutions. The structure of Cs3Cu2Cl.y,2H20 has been reported and the anion is shown in (184). The salts D2[CuX ] (D = the 2,4-dimethyl-... [Pg.318]
