Fig. 1. Stable compounds in the Sr-B-C system. (A) Ternary phase diagram at 50 GPa. Green circles represent thermodynamically stable compounds, while orange  squares represent metastable compositions used in the search
Fig. 2. Structure of SrB 3 C 3  clathrate. The cubic structure ( Pm   ¯  3 n ) is composed of face-sharing boron-carbon cages that encapsulate Sr 2+  cations
Fig. 3. XRD and equation of state of SrB 3 C 3 . (A) Experimental XRD data (black points) collected at 57(3) GPa with Rietveld refinement (blue line) of the SrB 3 C 3  phase
