摘要

A new series of coordination polymers, namely, CP2 [{(H2O)Co-1.5(mu-3-bpna)(1.5)(mu-btc)}center dot 3DMF center dot 3H(2)O]alpha, CP3 [{Cd(mu-3-bpna) (mu-hbtc)}center dot CH3OH center dot 2H(2)O](alpha), CP4 [{Co(mu-3-bpna) (mu-ipa)}center dot DMF-2H(2)O](alpha), CPS [{Co(mu-3-bpna)(mu-1,3-pda)}center dot DMF](alpha), CP6 [Cd(mu-3-bpna)(0.5)(mu-1,3-pda)(alpha), CP7 [(H2O)Co-0.5(mu-3-bpna)(0.5)(mu-1,4-pda)(0.5)](alpha), and CP8 [{Zn(mu-3-bpna)(mu-oba)}center dot DMF center dot 2H(2)O], has been synthesized by reacting a hydrogen-bond-functionalized bis-pyridyl ligand, namely, N',N ''-di(pyridin-3-yl)naphthalene-2,6-dicarboxamide, with various transition metal salts and different di- or tricarboxylates (as co-ligand) displaying 2D and 3D network topology and having lattice-occluded solvents in the majority of cases. A 1D coordination polymer, namely, CP1 [{Ag-0.5(mu-3-bpna)}(0.5)center dot 0.5BF(4)center dot CH3CN](alpha), has also been isolated by reacting 3-bpna with AgBF4 in the absence of any carboxylate co-ligand. All of the CPs were characterized by single crystal X-ray diffraction. Interestingly, two such CPs, namely, CP1 and CP2, produced metallogels, which were characterized by rheology, transmission electron microscopy, and X-ray powder diffraction. The metallogel of CP1 produced Ag nanoparticles within the gel bed upon exposure to light.
