原位同步辐射X-射线吸收测量进行估计液体SnI 4的密度。发现低压和高压液体的特征密度分别为4.6-4.7和4.9-5.0 g/cm 3，并且它们的区域在约1.7 GPa处分离。密度的差异，虽然0.3-0.4 g/cm 3的微小量，强烈地表明在两个液体区域之间的该压力下存在弱但不连续的相变。
An in situ synchrotron x-ray absorption measurement was carried out to estimate the density of liquid SnI4. The characteristic densities of the low- and high-pressure liquids were found to be 4.6–4.7 and 4.9–5.0 g/cm3, respectively, and their region is separated at around 1.7 GPa. The difference in density, although a slight amount of 0.3–0.4 g/cm3, strongly suggests the existence of a weak but discontinuous phase transition at that pressure between the two liquid regions.
