Both binary systems display the formation of one 2:1 mixed salt each (at x = 0.667) that appear as a peritectic (incongruent melting) at Tfus = 512.0 K, and Tfus = 461.1 K, with ΔfusHm = 13.76 and 8.08 kJ·mol-1 for Li-Tl (I) propanoates, and n-pentanoate mixed salts, respectively. The thermotropic liquid crystal of the thallium(I) n-pentanoate transforms into a more stable liquid-crystal phase, which appears in the phase diagram between 380 and 488 K and for x = 0 up to x = 0.56. The crystal structure of thallium(I) propanoate and of the two mixed salts were obtained via X-ray synchrotron radiation diffraction measurements. These compounds present a bilayered structure similar to the two pure lithium salts previously found by our group.engjournal articlehttp://dx.doi.org/10.1021/jp1031702restricted access546.34546.683544.25Cristalografía (Geología)GeoquímicaMineralogía (Geología)Química física (Química)2503 Geoquímica2506.11 Mineralogía
