摘要The title complex [Na(H2MIA-)(H2O)] (1, H3MIA = 2-methyl-1H-imidazole-4,5-dicarboxylic acid) has been synthesized by hydrothermal synthesis and structurally characterized by X-ray crystallography. Compound 1 crystallizes in orthorhombic, space group ibam with a = 14.4737(19), b = 17.553(2), c = 6.5285(9) Å, V = 1658.6(4) Å3, C6H7N2NaO5, Mr = 210.12, Z = 8, Dc = 1.675 g/cm3, F(000) = 864, μ = 0.188 mm-1, λ(MoKα) = 0.071073 Å,R = 0.0383 and wR = 0.0987 for 1046 observed reflections (I > 2σ(I)). In the structure of 1, each coordination water coordinates with two Na(I) ions at the same time and links the neighboring Na(I) ions to form a one-dimensional Na(I)-water chain. Each H2MIA- ligand links the neighboring Na(I) of Na(I)-water chain to form a novel two-dimensional supramolecular network. The 2-D network is stablied by O-H...N hydrogen bonds and π-π interaction. The 2D network is further linked via O-H...O hydrogen bonds to yield a three-dimensional framework.
