An astonishing amount of methane is reversibly adsorbed in pores of CuSiF6 (4, 4′-bipyridine) 2n, which exists as a stable 3D microporous network (see picture). The approximate channel sizes of this material is 8×8 Å2 along its c axis and 6×2 Å2 along the a and b axes. At 36 atm, the density of methane adsorbed in micropore volume is 0. 21 g mL−1, which is superior to that of any reported zeolites.
