Al 3Q MAS NMR spectroscopy has been applied to study small amount of pentacoordinated Al emerges. The majority of the signal, however, arises from distorted tetrahedral Al. the coordination state of the species giving the 30 ppm Al NMR signal in the 27 Al MAS NMR spectrum of activated A two-step cal
