    Abstract
  • The title complex, ] <em>n( 1 ) was synthesized by liquid/liquid diffusion method at room temperature. The complex crystallizes in monoclinic, space group P2(1)/C, with a0.877?5(6)nm, b1.171?5(8)nm, c0.751?8(5)nm, V0.739?3(9)nm 3, C 10H 14CoN 4O 8, M r377.18, D c1.694?g/cm 3, μ1.210?mm -1, F(000)386, Z2, the final R0.022?9 and wR0.066?1 for 3?137 observed reflections ( I>2σ(I)). In the structure of 1 , the center atom of cobalt revealed a centrosymmetric, six-coordinate structure, with two Py ligands, two monodentate nitrate groups and two water molecules. It is notable that a series of hydrogen bonds (O—H…O) formed two kinds of rings exist in the structure, which linked neighboring six-coordinate polymer into a two-dimensional H-bonding network, and then assembled into a three-dimensional supramolecular architecture through electrostatic and hydrophobic interaction. In the structure, supramolecular sheet was observed, which contains alternative organic and inorganic layers.
