Abstract:
Solid Pb3O4 has been studied with Full-size image (<1 K) nuclear magnetic resonance (NMR) spectroscopy. The Full-size image (<1 K) NMR chemical-shift tensor of the Pb2+ site has principal values of δ11=1980±5 ppm, δ22=1540±5 ppm, and δ33=−1108±10 ppm; δiso=804±10 ppm. The chemical-shift tensor of the Pb4+ site is axial, with principal values δ‖=−1009±3 ppm and δ⊥=1132±3 ppm; δiso=−1091±3 ppm. The Pb4+–Pb2+ scalar coupling constant JPb–Pb=2.3±0.1 kHz. The main contribution to the Pb2+ chemical-shift anisotropy is proposed to arise from an exchange interaction in the Pb2+–Pb2+ pairs, conventionally regarded as molecular [Pb2]4+ ions.
