Three new coordination complexes based on 2-methyl-4, 5-imidazoledicarboxylic acid varying from zero- to two-dimensionality
Reaction of 2-methyl-imidazole-4,5-dicarboxylic acid (H3MIDC) with different salts (Zn and Mn) has led to three new HnMIDC-metal complexes varying from zero- to two-dimensional structures under hydrothermal and solvothermal conditions. The complex [Zn(H2MIDC)2(H2O)2] (1) is a 0-D complex constructed by H2MIDC- and Zn centers and the complex [Mn(HMIDC)(H2O)2] · H2O (2) is a polymeric 1-D chiral chain constructed by HMIDC2- and Mn centers connected into a 3-D supramolecular framework with a 1-D channel. The complex [Zn3(MIDC)2(H2O)2(DMF)2] · 0.5H2O (3) shows a 2-D puckered structure composed of MIDC3- and Zn. The differences of the three complexes demonstrate that reaction solvent and temperature have important effects on the structure of these complexes. Complex 3 shows strong fluorescence in the solid state at room temperature.
