Description	We synthesized and characterized (Bi0.4Sr0.6)Sr2CoO5?delta using X-ray diffraction (XRD) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS). In the next step the heat capacity and enthalpy increments of (Bi0.4Sr0.6)Sr2CoO5?delta were measured by physical property measurement system (PPMS), differential scanning calorimetry (DSC) and drop calorimetry. Oxygen non-stoichiometry was determined using thermogravimetric measurement (TG) and reduction in hydrogen atmosphere. Above room temperature the temperature dependence of the molar heat capacity in the form C pm = (201.0 + 0.09261 x T ? 2184097 x T ?2) J K?1 mol?1 was derived by the least squares method from the experimental data. The heat capacity was also analyzed in terms of a combined Debye-Einstein model. The molar entropy View the MathML sourceSm° (298.15) = 219.65 J mol?1 K?1 was evaluated from the low temperature heat capacity data We synthesized and characterized (Bi0.4Sr0.6)Sr2CoO5?delta using X-ray diffraction (XRD) and scanning electron microscopy with energy dispersive spectroscopy (SEM-EDS).
