Tuning Magnetic Relaxation Pathways in Erbium Single-Ion Magnets Via Aromatic Cyclopentadienyl Substitution

In this work, the pentamethylcyclopentadienyl ligand in the archetypal organometallic erbium singleion magnet COTErCp* ( Er Me ) was replaced by a pentaphenylcyclopentadienyl ligand, affording a new complex COTErCp Ph5 ( 1Er ). With similar...
