Abstract:

A Mg(II) complex, [MgL·(H2O)3]·2H2O (H2L = 2,6-pyridinedicarboxylic acid), has been synthesized and characterized by elemental analysis, IR and X-ray single crystal diffraction analysis. The Mg(II) complex belongs to monoclinic, space group P21/n with a = 8.9318(18) Å, b = 10.002(2) Å, c = 13.290(3) Å, β = 96.86(3)º, V= 1178.8(4) Å3, Z = 4, Dc = 1.575 mg·m-3, μ = 0.192 mm-1, F(000) = 584, and final R1 = 0.0349, ωR2 = 0.1212. Structural analysis shows that the Mg(II) center is six-coordination with a NO5 distorted octahedral coordination environment. The Mg(II) complex forms 1D chain structure by the interaction of hydrogen bonds and π-π stacking.
