Preparation and isomerism
It is prepared from IrCl3(H2O)3 and acetylacetone. The complex has been resolved into individualenantiomer
In chemistry, an enantiomer ( /ɪˈnænti.əmər, ɛ-, -oʊ-/ ''ih-NAN-tee-ə-mər''; from Ancient Greek ἐνάντιος ''(enántios)'' 'opposite', and μέρος ''(méros)'' 'part') – also called optical isomer, antipode, or optical ant ...
s by separation of its adduct with dibenzoyltartaric acid.
A second linkage isomers is also known. In the second isomer one of the acetylacetonate ligands is bonded to Ir through carbon.
Uses
The O6-bonded isomer has been investigated for usechemical vapor deposition
Chemical vapor deposition (CVD) is a vacuum deposition method used to produce high quality, and high-performance, solid materials. The process is often used in the semiconductor industry to produce thin films.
In typical CVD, the wafer (substra ...
