Abstract

Atomic hydrogen has been stably encapsulated in both solution and crystal at room temperature. Upon γ-ray irradiation of [(CH₃) ₃Si]₈Si₈O₂₀, which is the trimethylsilylated derivative of the silicate anion with a double four-ring (D4R) cage, electron spin resonance (ESR) spectra revealed that a single hydrogen atom is encapsulated in the center of the D4R cage and is stable for periods of many months. Attack by chemically reactive species such as oxygen was prevented by the D4R cage, but the ESR signal of the hydrogen atom was sensitive to the magnetic interaction caused by the presence of the O ₂ molecule near the cage.
