Melting / freezing point at 101 325 Pa:
205 K

Additional information

Three different reliable handbook and database sources stating values of the same order of magnitude. The same value cited by two different sources was chosen as key parameter. There is sufficient information to conclude that melting is well below coldest environmental conditions experienced.
