Jacutingate, a recently discovered Brazilian naturally occurring mineral, has shown to be the first experimental realization of the Kane-Mele topological model. In this letter we have unveiled a class of materials M2NX3 (M=Ni, Pt, Pd; N=Zn, Cd, Hg; and X=S, Se, Te), sharing jacutingaite's key features, i.e., high stability, and topological phase. By employing first-principles calculations we extensively characterize the energetic stability of this class while showing a common occurrence of the Kane-Mele topological phase. Here we found Pt-based materials surpassing jacutingaite's impressive topological gap and lower exfoliation barrier while retaining its stability.
