ResumoAbstract Complex formation parameters of macrotetrolide antibiotics with alkali and alkaline earth metal cations are given. The stability constants for the complexes in methanol and ethanol at 30°, as determined by vapour pressure osmometry, and ΔH 0 , ΔG 0 , and ΔS 0 for some interactions in methanol and ethanol at 25°, measured by microcalorimetry, are compared and discussed.
