The heat capacity (Cp) of Nb3, is measured at 12 to 300 K. At low temperatures Cp varies quadratically with temperature. The experimental Cp values are in qualitative agreement with the known features of the low dimensionality of the NbS3 crystals which have a well-defined two-dimensional (layer) structure.
