Fig. 1. (a) Synchrotron PXRD profiles of 1-dmen, 1-dmen-CO2 , and 1-dmen-re. (b) Enlargement of the low-angle region of the PXRD data. (c) Framework structure of 1 with open metal sites, grafting modes of dmen onto the open metal sites, and subsequent CO2 adsorption. The schematic diagram (bottom) indicates the arrangement of ammonium carbamates running along the c-axis.
