  "abstract": "The exploration of metallicity in two-dimensional coordination polymers (2D CPs) remains challenging but crucial for their development toward various applications in electronics and thermoelectrics. Here, we report the low-temperature electronic transport properties of a 2D CP, copper(I)-1,3-benzenedithiolate, [Cu₂(1,3-BDT)]n. A semiconductor-to-metal transition in electrical resistivity is observed below 150 K. This transition is accompanied by a sign change and the emergence of large negative Seebeck coefficient values, shifting from a few hundred positive μ V K−1 to negative values in the mV K−1 range, as well as the onset of paramagnetism at low temperatures in the magnetic susceptibility. Based on first-principles calculations, these observations are attributed to an intrinsic temperature-driven drift of the electrochemical potential between the edges of two electronic state distributions separated by a small energy gap.",
