Three amorphous coordination polymers, R2dtoaCu, where R=CH3, C6H5CH2, or cyclohexyl and dtoa=(N,N'-disubstituted dithiooxamidato), were prepared and the effect of uniaxial pressure on their electrical resistivities in the direction of the external pressure was measured.Application of the pressure up to 6*108 Pa caused an increase in the resistivity but, before reaching the equilibrium state, the resistivity exhibited a complicated time variation, which was not completely reversible upon pressure release as far as the measurement could trace.The results were explained on the basis of a model in which at least two competing processes occur.One of the processes is assumed to be reorientation of the two-dimensional network of molecules perpendicular to the applied pressure, which is a slow process and takes as long as hundreds of hours to reach the equilibrium.Activation energies of various processes were derived.
