A neutral 3D metal-organic framework, (3)(infinity)[Cu-2(mand)(2)(hmt)]center dot H2O (1), was constructed from binuclear Cu2O2 alkoxo-bridged nodes, generated by the doubly deprotonated mandelic acid. The nodes are connected by hexamethylenetetramine (hmt) spacers, which act as biconnective bridging ligands, and by carboxylato groups. Channels are observed along the crystallographic c axis. The water molecules from the channels can be easily removed, preserving the architecture of the crystal, which is stable up to 280 degrees C. The Langmuir surface area was found to be 610 m(2) g(-1). The sorption ability of 1 was investigated using H-2 and CO2.
