(a) The powder X-ray diffraction patterns of complex (I) and (b) the N2 and CO2 adsorption isotherm (273 K) of (I). Key: square and triangle curves represent N2 and CO2 adsorption respectively, filled shapes represent adsorption and open shapes represent desorption. In (a), `activated' is the pattern from the crystal sample by heating under a vacuum pretreatment at an optimized temperature of 413 K for 20 h, `simulated' is the pattern from the CIF produced by Mercury (Macrae et al., 2008) and `as synthesized' is the pattern from the synthesized crystal. |
