We have studied fluid-solid phase transformations of materials interacting via the Dzugutov potential (Phys. Rev.A 46, R2984 (1992)). We present evidence from molecular dynamics simulations that this interaction does not exhibit a liquid phase. If a mixed potential Vmix(r) is formed by a linear superposition of and the Lennard-Jones potential , then the liquid phase disappears at a fraction of less than 60% .
