Indenyltrioxorhenium(VII), (C9H7)ReO3, was synthesized from Re2O7 and (indenyl)tris(n-butyl)tin.It is a moisture- and temperature-sensitive compound (dec. -30 deg C), the structure of which adopts η¹-coordination of the organic ligand.According to 1H NMR studies, a haptotropic structural rearrangement occurs at > -25 deg C in solution (1,3-shift mechanism).Decomposition studies show a concentration decay of the title compound in anhydrous solution, with formation of ReO3 and indene.Keywords: Rhenium; Indenyl; Dynamic structure; NMR
