The complex is widely used precursor to other iridium complexes. A notable derivative is Crabtree's catalyst. [5] The chloride ligands can also be replaced with methoxide to give cyclooctadiene iridium methoxide dimer, Ir 2 (OCH 3) 2 (C 8 H 12) 2. [6] The cyclooctadiene ligand is prone to isomerize in cationic complexes of the type [(C 8 H 12 ...
Iridium-192 is a very strong gamma ray emitter, with a gamma dose-constant of approximately 1.54 μSv·h −1 ·MBq −1 at 30 cm, and a specific activity of 341 TBq·g −1 (9.22 kCi·g −1). [ 14 ] [ 15 ] There are seven principal energy packets produced during its disintegration process ranging from just over 0.2 to about 0.6 MeV .
