文摘

A neutral 3D metal鈥搊rganic framework, ³_{鈭?/sub>[Cu2(mand)2(hmt)]路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 掳C. The Langmuir surface area was found to be 610 m² g^鈥?. The sorption ability of 1 was investigated using H2 and CO2.}
