Synthesis, characterization, and crystal structure of a new coordination polymer, {[Ba₂(Hpydc)₂(pydc)(H₂O) ₃].H₂O.(H₂pydc)}_n

چکیده مقاله

The reaction of barium chloride with 2,6-pyridinedicarboxylic acid, H ₂pydc, in water led to the formation of a novel polymeric complex formulated as {[Ba₂(Hpydc)₂(pydc)(H₂O) ₃].H₂O.(H₂pydc)}_n, (I). The crystal structure of (I) was characterized by X-ray diffraction methods. This polymeric complex was crystallized in the monoclinic system with space group P2/c, with four molecules per unit-cell. The unit-cell parameters are a = 15.320(3) A̧, b = 6.902(1) A̧, c = 19.930(4) Å; β = 97.39° (3). The unit-cell of this novel self assembled pyridine containing ligand system was constructed from eight and ten coordinate barium ions. Noteworthy, compound (I) consisted of neutral 2,6-pyridinedicarboxylic acid, H₂pydc, anionic Hpydc^- and pydc^2-. © 2008 Chemical Society of Ethiopia.
