Synthesis and Characterization of a Novel Hydrogen-Bonded Three-dimensional Porous Co(II)Compound |
| |
| Abstract: | A hydrogen-bonded three-dimensional cobalt(II) compound, {Co(2,2?-bipy)- (Hbtc)(H2O)3]3H2O}n 1 (H3btc = 1,3,5-benzenetricarboxylic acid, 2,2?-bipy = 2,2?-bipyridine), has been synthesized and characterized by single-crystal X-ray diffraction analysis, IR and TGA. Compound 1 crystallizes in monoclinic, space groups P21/n, C19H36CoN2O12, Mr = 543.43, a = 7.6930(2), b = 19.3715(6), c = 15.9408(5) , = 95.8750(10)o, V = 2363.10(12) 3, Z = 4, Dc = 1.527 g/cm3, = 0.792 mm1, F(000) = 1148, R = 0.0489 and wR = 0.1437 for 4085 reflections. The Co(II) atom is coordinated by an oxygen atom of monodentate Hbtc2, two nitrogen atoms of 2,2?-bipy and three water molecules into a slightly distorted octahedral geometry. The inter- molecular hydrogen bonding interactions among the adjacent Co(2,2?-bipy)(Hbtc)(H2O)3] extend the compound into a three-dimensional porous supramolecular framework. The uncoordinated water molecules act as space-fillers and consolidate the whole architecture through the hydrogen bonding interactions. |
