<jats:title>Abstract</jats:title> <jats:p>The hydrogen adsorption properties and uptake capacities of three-dimensional microporous materials of lantern-type dinuclear M(BDC)(DABCO)1⁄2 (M=CoII, CuII, and ZnII; BDC = 1,4-benzenedicarboxylate, DABCO = 1,4-diazabicyclo[2.2.2]octane; Co(BDC)(DABCO)1⁄2 (1), Cu(BDC)(DABCO)1⁄2 (2), Zn(BDC)(DABCO)1⁄2 (3)) were investigated at various temperatures of 77–333 K and pressures up to 10 MPa using a PCT automatic measuring system (Sievert-type apparatus). The results indicated that uptake to 4.11, 2.70, and 3.17 wt % of hydrogen can be stored on 1, 2, and 3, respectively, at 77 K. The amounts of hydrogen are adsorbed by all complexes at around room temperature (293 K) and high-pressures are much lower (<0.5 wt %). Adsorption isotherms at around room temperature show a linear uptake relationship; all of them follow the Henry’s law. By measuring nitrogen gas adsorption/desorption, all complexes exhibit approximately Type-I isotherms according to the IUPAC classification and possess BET surface areas in the range of 1165 (for 3) to 1595 m2 g−1 (for 1). Further, the thermal stability of all complexes is high, in the range of about 500 K (for 3) to 600 K (for 1). These complexes were synthesized and characterized by X-ray powder diffraction pattern, TG/DTA, FT-IR, surface area analysis, and hydrogen adsorption measurements.</jats:p>
