Melting Point
At 260 K, a first-order phase transition from face-centered cubic crystal structure to a simple cubic structure is observed, accompanied by a lattice contraction. ... At 90 K the molecules rearrange to attain the best global minimum. ... At this temperature, the rotational degrees of freedom are frozen, and the solid structure is designated as a pseudo-face-centered cubic crystal structure. C70 Fullerene is rotationally disordered at room temperature and undergoes a transition to a low-temperature phase.
