The synthesis, X-ray structure, and magnetic properties of a new aminoxyl biradical linked by a silacyclopentadienyl ring is reported. Connection across the 2,5-positions of the silole is characterized by intramolecular antiferromagnetic interactions leading to a singlet ground state, which is one of the requirements for accessing photoinduced/photoswitching magnetic spin systems.
