Hydrogen-adsorption properties of a novel lantern-type dinuclear Co(BDC)(DABCO)1/2

A three-dimensional (3-D) cobalt coordination polymer Co(BDC)(DABCO) 1/2 (BDC = 1,4-benzenedicarboxylate; DABCO = l,4-diazabicyclo[2.2.2]octane), which has a novel lantern-type structure, was synthesized and characterized by X-ray powder diffraction patterns and elemental analysis. In addition, hydrogen-adsorption characteristics were evaluated at 77 K. The highest measured hydrogen uptake was 2.28 wt % at 77 K and 0.1 MPa for Co(BDC)(DABCO) 1/2 .
