Abstract

The Knudsen cell mass spectrometric method has been employed to measure the partial pressures of Snn (n=1–7) under equilibrium conditions above liquid tin or a tin–gold alloy, contained in a graphite Knudsen cell. From the all-gas analyzed equilibria the following atomization enthalpies ΔaH0∘(Snn), and enthalpies of formation, ΔfH298.15∘(Snn), in kJ mol−1, have been obtained: Sn4, 750.2±14 and 450.6±14; Sn5, 990.2±22 and 512.3±22; Sn6, 1349.7±28 and 452.8±28; Sn7, 1644.2±37 and 460.0±37. The atomization energies are compared with available theoretical values.
