Tin at a pressure of 39 kb and at 314 ° C has tetragonal symmetry with an atom at each point of a body-centered tetragonal lattice. The unit cell dimensions are a equal to 3.81 A, c equal to 3.48 A, and c/ a = 0.91. The melting curve of tin was observed up to 45 kb and the boundary line between the tin I and tin II phases was observed to 70 kb by x-ray diflraction techniques.
