  摘要：

  Four new coordination networks based on dipyridyl linkages 2,6-(N,N'-di(4-pyridyl)amino)pyridine (dpap) or 1,3-bis(4-pyridyl)propane (bpp) and different dicarboxylates have been synthesized and structurally characterized. Using dpap to react with two different dicarboxylates, maleic acid (H(2)mal) and 4,4'-sulfonyldibenzoate (H(2)sdba), respectively, two different two-dimensional (2D) coordination polymers of Cd(II), [Cd(dpap)(mal)](n) (1) and {[Cd(dpap)(sdba)] center dot 2H(2)O}(n) (2) were obtained. Compound 1 features a 42-membered bimetallic macrocyclic structural motif which is extended by mal groups to form a 2D network. In the case of 2, two different layers can be achieved depending on the conformation of sdba. The layer has a (8(2)10) net topology with Cd as nodes and dpap, sdba bridges as the connectors. The overall structure of {[Mn(dpap)(sdba)] center dot 1.5H(2)O}(n) (3) similar to that of 2 despite the presence of different metal ions. When dpap was replaced by bpp to react with Co(NO3)(2) center dot 6H(2)O, another 1D coordination polymer, {[Co(bpp)(H2O)(4)] center dot sdba}(n)(4) was constructed. The 1D chains join sdba to make an overall 3D supra-molecular architecture by hydrogen-bonding interactions (R-2(4) (22), R-2(4) (12)). The Cd coordination polymers exhibit strong solid-state luminescence emission at room temperature. Thermal stability of these crystalline materials has been explored by thermogravimetric analysis of mass loss. (C) 2008 Elsevier B.V. All rights reserved.

  Four new coordination networks based on dipyridyl linkages 2,6-(N,N'-di(4-pyridyl)amino)pyridine (dpap) or 1,3-bis(4-pyridyl)propane (bpp) and different dicarboxylates have been synthesized and structurally characterized. Using dpap to react with two different dicarboxylates, maleic acid (H(2)mal) and 4,4'-sulfonyldibenzoate (H(2)sdba), respectively, two different two-dimensional (2D) coordination polymers of Cd(II), [Cd(dpap)(mal)](n) (1) and [Cd(dpap)(sdba)] center dot 2H(2)O}(n) (2) were obtained. Compound 1 features a 42-membered bimetallic macrocyclic structural motif which is extended by mal groups to form a 2D network. In the case of 2, two different layers can be achieved depending on the conformation of sdba. The layer has a (8(2)10) net topology with Cd as nodes and dpap, sdba bridges as the connectors. The overall structure of [Mn(dpap)(sdba)] center dot 1.5H(2)O}(n) (3) similar to that of 2 despite the presence of different metal ions. When dpap was replaced by bpp to react with Co(NO3)(2) center dot 6H(2)O, another 1D coordination polymer, [Co(bpp)(H2O)(4)] center dot sdba}(n)(4) was constructed. The 1D chains join sdba to make an overall 3D supra-molecular architecture by hydrogen-bonding interactions (R-2(4) (22), R-2(4) (12)).
