It is a long-thought proposal that dense light-element molecular hydrides, such as diborane (B2H6) and methane (CH4), offer an ideal platform to search for phonon-mediated superconductors. However, these hydrides are often unstable under sufficiently high pressure, e.g., B2H6 decomposed into BH and H2 at pressures of above 153 GPa, which are unlikely to exhibit high superconductivity.
