Abstract

A tetraphenylporphyrin based Tb^III double-decker complex has been synthesized and the crystal structure of both protonated and deprotonated forms has been determined. The ac magnetic susceptibility measurements revealed that the SMM properties of the double-decker complex can be reversibly switched by only a single proton.
