Abstract
Results are presented on the temperatures, enthalpies, and entropies of the phase transitions of the even chain length copper(II) carboxylates from decanoate to octadecanoate. The dodecanoate, tetradecanoate and hexadecanoate melt directly from crystal to isotropic liquid. However, with the decanoate and octadecanoate, an intermediate phase is observed between solid and isotropic liquid. Tentative assignments are made on the intermediate phases. Electronic and infrared spectra are reported for the solid copper(II) carboxylates. In both cases, the spectra provide clear evidence for there being at least two copper ions in the head-group region of each copper carboxylate system.
