Bis(η2-ethylene)(η5-indenyl)iridium(I) was written by Merola, Joseph S.. And the article was included in Acta Crystallographica, Section E: Structure Reports Online in 2013.Application of 39722-81-1 This article mentions the following:
The asym. unit of the title compound, [Ir(C9H7)(C2H4)2], consists of two independent mols. crystallog. data and at. coordinates are given. The bonding between Ir and the five-membered ring of the indenyl ligand shows the usual asymmetry associated with the typical ring slippage responsible for the enhanced activity of indenyl metal compounds when compared with the analogous cyclopentadienyl metal compound There are three short Ir-C bonds of 2.210(3), 2.190(4) and 2.220(3) Å and two long Ir-C bonds to the C atoms that are part of the fused six-membered ring of 2.349(4) and 2.366(3) Å for one of the independent mols. [2.208(4), 2.222(3), 2.197(4) Å for the short distances and 2.371(3) and 2.358(3) Å for the long distances in the 2nd mol.]. This results in both indenyl ligands being slightly kinked, with dihedral angles of 6.8(4)° and 6.5(4)°. In the experiment, the researchers used many compounds, for example, Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1Application of 39722-81-1).
Chlorobis(ethylene)iridium(I) dimer (cas: 39722-81-1) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Application of 39722-81-1
