Calculated values of the thermodynamic functions [ Aston J.D., 1946, Kilpatrick J.E., 1946, Durig J.R., 1980, Thermodynamics Research Center, 1997] show some disagreement between authors as well as with experimental data [ Aston J.D., 1946, 2, Wacker P.F., 1947] (up to 3-4 J/mol*K). More reliable experimental data are required to solve available inconsistency.; GT
