Tris(η5-2,4-cyclopentadien-1-yl)gadolinium

Description:
Tris(η5-2,4-cyclopentadien-1-yl)gadolinium, with the CAS number 1272-21-5, is a coordination compound featuring gadolinium, a rare earth metal, coordinated to three cyclopentadienyl ligands. This compound exhibits a unique structure characterized by the presence of cyclopentadienyl rings, which are known for their ability to stabilize metal centers through π-bonding. The gadolinium ion in this complex typically exhibits a +3 oxidation state, contributing to its paramagnetic properties, which are significant in various applications, including magnetic resonance imaging (MRI) and materials science. The compound is generally soluble in organic solvents, reflecting the non-polar nature of the cyclopentadienyl ligands. Its synthesis often involves the reaction of gadolinium salts with cyclopentadiene derivatives. The presence of multiple cyclopentadienyl groups enhances the stability and reactivity of the gadolinium center, making it a subject of interest in organometallic chemistry and potential applications in catalysis and electronic materials. Safety precautions should be observed when handling this compound due to the toxicity associated with gadolinium and its compounds.
