• We report the results of the study of thermodynamic properties for layered perovskite-like oxides NaNdTi[O.sub.4] and [Na.sub.2][Nd.sub.2][Ti.sub.3][O.sub.10]. Isobaric heat capacity of the compounds was measured in an adiabatic calorimeter in the range of 5-340 K. Low-temperature heat capacity anomaly was observed in the heat capacity curve of [Na.sub.2][Nd.sub.2][Ti.sub.3][O.sub.10]. Standard thermodynamic properties of the oxides were evaluated from the experimental heat capacity temperature dependencies. Finally, on the basis of the experimental data obtained in this work, we tested applicability of the additivity principle for prediction of thermodynamic properties for layered compounds built of fragments of various structural types.
