Trimethylolpropane phosphite, C2H5C(CH2O)3P, is a phosphite ester
used as a ligand
in organometallic chemistry
. Trimethylolpropane phosphite is sometimes abbreviated to EtCage. Several EtCage complexes have been synthesised and studied to date, including [(EtCage)2Mo(CO)4], [Ir4(CO)11(EtCage)] and (CpMe5)RuCl(EtCage)2, shown below.
Phosphite ester
A phosphite ester or organophosphite is a type of chemical compound with the general structure P3. Phosphite esters can be considered as esters of phosphorous acid, H3PO3. A simple phosphite ester is trimethylphosphite, P3...
used as a ligand
Ligand
In coordination chemistry, a ligand is an ion or molecule that binds to a central metal atom to form a coordination complex. The bonding between metal and ligand generally involves formal donation of one or more of the ligand's electron pairs. The nature of metal-ligand bonding can range from...

Organometallic chemistry
Organometallic chemistry is the study of chemical compounds containing bonds between carbon and a metal. Since many compounds without such bonds are chemically similar, an alternative may be compounds containing metal-element bonds of a largely covalent character...
