Investigates superconducting properties in ternary hydride, suggesting novel stabilization mechanisms.
Li 2 PbH 4 is dynamically stable at 34 GPa with a T c of up to 123 K. Li dissociates H 2 via charge transfer and precompresses the 3D Pb–H cage, optimizing electronic states to boost electron–phonon coupling, achieving low-pressure stability and high T c .
