Abstract We investigate the structural properties of liquid Sn. With the help of the internal friction (tanФ) method, it is found that a peak appears in the tan Ф-T curve, suggesting that an anomalous discontinuous temperature-induced structure change may take place in liquid Sn. From the experimental data of pair distribution functions, we calculate the viscosity η and the excess entropy S and it is found that there are a peak of viscosity in the η-T curve and a bend of excess entropy in the S-T curve, which give a positive support to the appearance of the internal-friction peak in the tan Ф-T curve.
