The application of the scale-down chemistry through the use of the short and inexpensive BDC and IN ligands leads to a smaller pore size and lower surface area but little compromise in H<sub>2</sub> sorption properties. The compound exhibits a high CO<sub>2</sub> uptake of 73.1 cm<sup>3</sup> g<sup>–1</sup> (273 K and 1 atm) despite its moderate Langmuir and BET surface areas (888.3 and 571.0 m<sup>2</sup> g<sup>–1</sup>, respectively). Its H<sub>2</sub> uptake (1.47 wt % at 77 K and 1 atm) is also quite high, comparable to that of many materials with high surface area.
