Tantalum (V ) ethoxide is a chemical compound from the group of tantalum compounds and alcoholates.

Production and representation

Tantalum (V ) ethoxide can be obtained by reaction of tantalum pentachloride and ethanol in solvents such as benzene or toluene.

Properties

Tantalum (V ) ethoxide is a compound having a melting point of 21 ° C. Above this temperature is a colorless flammable liquid with a sweet odor before. Below the melting point of the compound forms a colorless solid. In the solid state are sixteenth -coordinate dimers in Forme of a Doppeloktaeders. In solvents with donor properties of a monomer is formed, the sixth coordination site is occupied by a solvent molecule. In water, dissolve tantalum (V ) ethoxide with hydrolysis.

Use
