      abstract = {We predict superconductivity for the carbon--boron  clathrate ${\mathrm{SrB}}_{3}{\mathrm{C}}_{3}$ with  ${T}_{c}=27\text{--}43\phantom{\rule{0.28em}{0ex}}\mathrm{K}$  for Coulomb pseudopotential (μ <sup>∗</sup>)values between  0.17 and 0.10 using first-principles calculations with  conventional electron--phonon coupling. Electrical  transport measurements, facilitated by an in situ  experimental design compatible with extreme synthesis  conditions ($>3000\phantom{\rule{0.28em}{0ex}}\mathrm{K}$  at 50 GPa), show nonhysteretic resistivity drops that track  the calculated magnitude and pressure dependence of  superconductivity for μ <sup>∗</sup> ≈ 0.15, and transport  measurements collected under applied magnetic fields  indicate superconductivity with an onset ${T}_{c}$ of  approximately 20 K at 40 GPa. Carbon-based clathrates thus  represent a class of superconductors similar to other  covalent metals like ${\mathrm{MgB}}_{2}$ and doped  fullerenes. Carbon clathrates share structures similar to  superconducting superhydrides with wide potential for  tunable properties, and covalent C--B bonds allow  metastable persistence at ambient conditions.},
