We report the gas sorption ability of [Cd(mu-hmt)(mu-dca)(2)](n), (1) (hmt = hexamethylenetetramine, dca = dicyanamide), a coordination polymer with 2D rectangular grid structure known as the porous non-porous materials, for CO2, CH4, and N-2 under different temperatures (295 K, 195 K). It was observed that polymer adsorbs CO2 and CH4, but not N-2 even at low temperature. Also, since electron transfer behavior of 1 has an important role on gas adsorption, electrochemical properties of polymer and its metal (cadmium) in absence and presence of hmt, are studied by cyclic voltammetry. In addition, thermal stability of 1 is investigated by thermogravimetric (TGA) analysis. To gain a deeper insight into the observed gas uptake of mentioned polymer, theoretical calculations have been used to study intermolecular interactions and characterize the bonding of gas sorption.
