Abstract: A combination of topological band theory, $k\ensuremath{\cdot}p$ modeling, and first-principles calculations leads to the prediction of a new class of topological crystalline insulators with antiperovskite structure, i.e. a perovskite with the positions of the rare-earth or alkaline-earth and oxygen atoms inverted. The authors predict that Ca${}_{3}$PbO and Sr${}_{3}$PbO are two representative examples from that class.
