This work describes the crystallographic, spectroscopic, and magnetic characterization of the homoleptic and distorted tetrahedral [V(OAd)4] (1), the only nonoxido vanadium(IV) alkoxide of its kind crystallized to date. Magnetization dynamics measurements by AC susceptometry revealed field-induced slow spin relaxation comparable to that of other vanadium(IV) potential molecular qubits. Coherence times of ca. 4 μs at low temperature have been disclosed by pulsed-electron paramagnetic resonance measurements.

Abstract
This work describes the crystallographic, spectroscopic, and magnetic characterization of the homoleptic and distorted tetrahedral [V(OAd)4] (1), the only nonoxido vanadium(IV) alkoxide of its kind crystallized to date. Magnetization dynamics measurements by AC susceptometry revealed field-induced slow spin relaxation comparable to that of other vanadium(IV) potential molecular qubits. Coherence times of ca. 4 μs at low temperature have been disclosed by pulsed-electron paramagnetic resonance measurements.
