Abstract
A mixed‐valence copper(I,II) coordination polymer [Cu^I^~2~Cu^II^(4,4′‐bpy)~2~(pydc)~2~]·4H~2~O (4,4′‐bpy = 4,4′‐bipyridine and pydc = pyridine‐2,4‐dicarboxylate) featuring the “metal‐complex ligands” [Cu^II^(pydc)~2~]^2−^ was designed and synthesized hydrothermally from Cu(MeCO~2~)~2~, pyridine‐2,4‐dicarboxylate, 4,4′‐bipyridine and NaOH. This compound was shown by single‐crystal structure analysis to be the first porous 3‐D framework constructed from fivefold parallel interpenetration of 2‐D (6,3) nets. The one‐dimensional channels occupying 17.4% of the crystal volume are occupied by guest water molecules and the porous network is stable after removal of the lattice water molecules, as indicated by TGA and PXRD measurements. The high stability of the 3‐D framework may be attributed to the multiple entanglement of the 2‐D nets. (© Wiley‐VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
