3D COBALT COORDINATION POLYMER:SYNTHESIS, AND CO2 ADSORPTION

The crystal structure and vibrational spectra of {(CH6N)[Co(CHO2)3]}n, the structure consists of a threedimensional net of central Co (II) ions connected via formate (methanediolate) bridges. The negative charge iscompensated by protonated methylamine cations. One of the Co (II) ions adopts a disordered octahedral geometry, coordinated by six O atoms from three different formate ligands. IR vibrational spectra were recorded and the full assignment of the vibrational frequencies is proposed. CO2 adsorption performances of the crystals were investigated at ambient temperature and pressure (1 atm), and diagram shows the corresponding CO2 adsorption–desorption isotherms of the crystals.
