Notes:
Sorption of ten different quantities of D2 within the porous coordination metal frameworkCu3(1,3,5-benzenetricarboxylate)2 were studied using neutron powder diffraction. D2 sorption in theporous material reached saturation (at 25 K) at an amount equivalent to ~6.5 wt. % H2. Rietveldanalyses revealed that at saturation there are two saturated small pore and three saturated large poresites, in addition to the primary site at the coordinatively unsaturated Cu. We reveal that the linkedbimodal pore system provides up to nine distinct sites for D2, at moderate D2 concentrations up tosaturation. Intermediate sites are attributed to local D2-D2 interaction within the confined porespaces. Within the small and large pores one, and two, intermediate sites are identified, respectively.The population of D2 at each site was found to affect the host lattice
