N2 - AC conductivity measurements with an impedance analyzer were carried out for a hydrogen-doped coordination polymer, N,N'-bis-(2-hydroxyethyl) dithiooxamidatocopper(II), in order to estimate the protonic conductivity (σp). The log σp was linearly increased from 2.6 χ 10-9 to 2.2 χ 10-6 S cm-1 with relative humidity (RH) from 45 to 100 % at 300 K. A slight hysteresis of protonic conductivity was observed upon increasing and decreasing RH, which implies that H3O+ is generated by a reaction between water molecule and acid-base polymer near RH - 100%.
