Yttrocene

Yttrocene is an organoyttrium compound with the chemical formula Y(C5H5)3. It forms light yellow crystals and can be obtained by reacting anhydrous yttrium(III) chloride and sodium cyclopentadienide in tetrahydrofuran. It decomposes when exposed to water to produce cyclopentadiene and yttrium(III) hydroxide. Its thermal stability is between ferrocene and other 3D transition metal tricene complexes.
