Two-dimensional cobalt-bipyridinedicarboxylate coordination polymer: [Co(2,2′-bipyridine-5,5′-dicarboxylato) (H2O)]·(H2O)

Hydrothermal reaction between cobalt(II) nitrate and 2,2′-bipyridine-5,5′-dicarboxylic acid in the presence of NaOAc gave a two-dimensional coordination-polymer of cobalt(II), [Co(2,2′-bipyridine-5,5′-dicarboxylato)(H2O)]·(H2O) (1). X-ray structure determination showed that compound 1 has a two-dimensional infinite network based on cobalt-bipyridinedicarboxylate building blocks and has a relatively small channel of 5.0×6.6 Å.
