Rb<sub>8</sub>B<sub>8</sub>Si<sub>38</sub> forms under high-pressure, high-temperature conditions at <i>p</i> = 8 GPa and <i>T</i> = 1273 K. The new compound (space group <i>Pm</i>3̅<i>n</i>, <i>a</i> = 9.9583(1) Å) is the second example for a clathrate-I borosilicide. The phase is inert against strong acids and bases and thermally stable up to 1300 K at ambient pressure. (Rb<sup>+</sup>)<sub>8</sub>(B<sup>-</sup>)<sub>8</sub>(Si<sup>0</sup>)<sub>38</sub> is electronically balanced, diamagnetic, ...[more]
