Abstract—The temperature dependences of saturated vapor pressure over M(PTA)2 · 15-crown-5, where M =
Ca, Sr, or Ba and PTA is the pivaloyltrifluoroacetonate anion, were studied by the Knudsen effusion method,
and the enthalpies of compound sublimation were calculated. Changes in volatility depending on the central
metal atom were determined.
