Cyclooctadiene iridium methoxide dimer is an
organoiridium compound with the formula Ir
2(OCH

2, where C
8H
12 is the
diene
In organic chemistry a diene ( ) (diolefin ( ) or alkadiene) is a covalent compound that contains two double bonds, usually among carbon atoms. They thus contain two alk''ene'' units, with the standard prefix ''di'' of systematic nomenclature. ...
1,5-cyclooctadiene. It is a yellow solid that is soluble in organic solvents. The complex is used as a precursor to other iridium complexes, some of which are used in
homogeneous catalysis
In chemistry, homogeneous catalysis is catalysis by a soluble catalyst in a solution. Homogeneous catalysis refers to reactions where the catalyst is in the same phase as the reactants, principally in solution. In contrast, heterogeneous catalysi ...
.
The compound is prepared by treating
cyclooctadiene iridium chloride dimer with sodium methoxide. In terms of its molecular structure, the iridium centers are square planar as is typical for a d
8 complex. The Ir
2O
2 core is folded.
