We study a simple and versatile diatomic potential function coined to preventcrystallization in supercooled liquids. We show that the corresponding liquiddoes not crystallize even with very long simulation runs at the lowesttemperature that we can access with ergodic simulations. The medium displaysthe usual features of supercooled materials and a non-Arrhenius dependence ofthe diffusion coefficient and alpha relaxation time with temperature. We alsoobserve the breakdown of the Stokes-Einstein relation at low temperatures.
