Iridium chloro 2-

Hexammino-iridium Chloro-iridite, [Ir(NHs)6][IrCl6], is precipitated as an amorphous yellow powder on the addition of potassium chloro-iridite to hexammino-iridium chloride. From dilute solution it crystallises in small quadratic plates. It is soluble in cold water, and fairly stable towards concentrated sulphuric acid, which only attacks it above 190° C. 

Chloro - pentammino - iridium Chloro - iridite, [Ir(NH3)5Cl]3 (IrCl6)2, is formed when the chloro-chloride is mixed with iridium trichloride. It separates as a flocculent yellow powder, and on recrystallising separates as a yellow crystalline powder. It is slowly attacked by sulphuric acid at 110° C.., and is decomposed on heating, yielding iridium, ammonium chloride, and hydrochloric acid.

There is a single crystal X-ray structure of (Ph4P)2[OsClg] which shows the mean Os—Cl distance to be 2.332 A, and unit cell data obtained for a number of cubic salts of [OsCl ] " and [OsBr ] -. In a recent paper correlations between Os—Cl distances and Os—Cl stretcMng frequendes have been made, and similar data presented for rhenium and iridium chloro species. In particular there have been a number of studies on the Raman spectra, both non-resonance and resonance, of [OsClj] as well as electronic and electronic resonance Raman spectra similar studies have been carried out with [OsBrJ " and [Oslj] " (for the latter, magnetic, electronic and Raman spectra and optical acti-vity were also measured ). In Table 27 we also... 

Cyclohexane was insufficiently reactive to give products in the CH2CI2 solvent used in the work described above, and iridium chloro complexes were formed instead, but on moving to neat alkane, several alkane-derived reaction products were seen as shown in equation 10. Particularly notable is the formation of fluorobenzene when L is (p- C U4,) P. This shows that the complex degrades by P—C bond cleavage, otherwise the reaction would probably be catalytic.
