Gadolinium (III ) Chloride / Gadolinium Trichloride

Gadolinium(III) chloride

Gadolinium(III) chloride, also known as gadolinium trichloride, is GdCl₃.

It is a colorless, hygroscopic, water-soluble solid. 

The hexahydrate GdCl₃∙6H₂O is commonly encountered and is sometimes also called gadolinium trichloride. 

Gadolinium(III) chloride, also known as gadolinium trichloride, is GdCl3. It is a colorless, hygroscopic, water-soluble solid. 

The hexahydrate GdCl3∙6H2O is commonly encountered and is sometimes also called gadolinium trichloride.

 Gd3+ species are of special interest because the ion has the maximum number of unpaired spins possible, at least for known elements. 

With seven valence electrons and seven available f-orbitals, all seven electrons are unpaired and symmetrically arranged around the metal. 

The high magnetism and high symmetry combine to make Gd3+ a useful component in NMR spectroscopy and MRI.
