The heat capacity and entropy of the four lithium stannides Li17Sn4, Li7Sn2, Li13Sn5 and Li7Sn3 in the temperature range (2 to 865) K

•High quality experimental heat capacity data of the lithium stannides Li17Sn4, Li7Sn2, Li13Sn5 and Li7Sn3 are reported.•To cover the broad temperature range from (2 to 665) K, two different calorimeters were applied.•The samples were characterized by XRD, chemical and thermal analysis.•Supply of the polynomial heat capacity function for four appropriate temperature intervals.•Computation of the standard entropy and entropy of formation.
