摘要：

Hydrothermal reaction of cobalt nitrate, phenylmalonic acid, and 4,4'-dipyridylamine (dpa) resulted in formation of the coordination polymer [Co-2(phaC)(4)(dPa)(2)(H2O)] (1, phac = phenylacetate), where the phac ligand is formed in situ by the decarboxylation of phenylmalonic acid. Binuclear [Co-2(phaC)(4)(H(2)0)] units with both bridging and monodentate benzenecarboxylate ligands are linked into a two-dimensional (4,4) rhomboid grid network via dpa tethers within the structure of 1. Use of benzoate as the anionic component allowed the formation of [Co(benzoate)(2)(dpa)(2)] (2), which manifested a dpa-linked one-dimensional chain coordination polymer motif with pendant monodentate and chelating carboxylates. Modest antiferromagnetic coupling was observed within the binuclear units in 1. (C) 2007 Elsevier B.V. All rights reserved.
