Thermodynamic anomaly of water is expected to be ascribable to the critical phenomena associated with the second（liquid-liquid）critical point, whose existence is, however, hardly proven directly. This is because the（hypothesized）point is thought to exist below the crystal homogeneous temperature, where no liquid bulk water can be probed. We have revealed that tin tetraiodide has quite a similar polyamorphic nature, but its second critical point is highly considered to lie in an accessible region.
