AB Lithium propanoate and pentanoate were characterized by DSC, single crystal and powder XRD and FTIR and impedance spectroscopies. Lithium propanoate presents a solid-to-solid transition (SII-SI) at Tss = (549.1 ± 0.7) K on first heating that varies on the second and next ones, followed by a fusion at Tf = (606.1 ± 0.5) K. For lithium pentanoate, two solid-to-solid transitions (SIII-SII and SII-SI), at T ss = (205.5 ± 0.5) K and Tss = (325.2 ± 0.7) K, respectively, and a melting point at Tf = (576.5 ± 0.3) K were found. The crystal structures for both compounds were characterized at 100 and 298 K (and for the lithium propanoate also at 160 K). Single-crystal XRD showed that the SII phase of both compounds has a monoclinic structure with the same symmetry group (P21/c). This is the first time that a single-crystal structure has been reported for any member of the lithium alkanoates series, so far. FTIR and impedance spectroscopies were also carried out to better characterize the solid phases in these compounds.
