The solvothermal reaction of In(iii) and 1,2,4,5-benzeneteracarboxylic acid with the presence of piperazine leads to the generation of a novel 3D chiral porous coordination polymer with PtS topological net. Interestingly, the resulting crystals were not a racemic mixture but enantiomeric excess, which was confirmed by the measurement of optical rotation of bulk samples using solid vibrational circular dichroism (VCD) spectra and the solid circular dichroism (CD) spectra based on large crystals from one crystallization. High-pressure CO2and CH4adsorption measurement at 298 K reveals that activated 1can absorb 45.8 cm3(STP)/g CO2at 22 atm and 22.5 cm3(STP)/g CH4at 25 atm. [ABSTRACT FROM AUTHOR]
