Two new coordination polymers, |DMF|[Zn2(C7N2O4H6)2(C10N2H8)] (1) and |(H2O)3|[Co(C8N2O4H9)2(H2O)2] (2) have been synthesized based on 2-ethyl-1H-imidazole-4,5-dicarboxylic acid (H3EtImDC) and 2-propyl-1H-imidazole-4,5-dicarboxylic acid (H3PrImDC) as organic ligands, respectively. Single-crystal X-ray diffraction analysis reveals that compound 1 is a two dimensional layered structure constructed from two types of six-membered metallocycle, and the layers are stacked in an –ABCABC– sequence. For 2, the mononuclear [Co(C8N2O4H9)2(H2O)2] molecules are connected with each other through hydrogen bonds forming a three dimensional supermolecular structure. Further characterizations including elemental analyses, IR spectra, and thermogravimetric analyses have been studied.
Compound 1 shows a 2D layered structure, which is generated from two types of six-membered metallocycle, and the layers are stacked in an -ABCABC- sequence. For 2, the mononuclear [Co(C8N2O4H9)2(H2O)2] molecules are connected with each other through hydrogen bonds forming a 3D supermolecular structure.Figure optionsDownload as PowerPoint slideHighlights
