An in situ synchrotron x-ray absorption measurement was carried out to estimate the density of liquid SnI<inf>4</inf>. The characteristic densities of the low- and high-pressure liquids were found to be 4.6--4.7 and 4.9--5.0 g/cm<sup>3</sup>, 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/cm<sup>3</sup>, strongly suggests the existence of a weak but discontinuous phase transition at that pressure between the two liquid regions.
