• Two main group coordination polymers based on H4hmIDC are constructed.
• The layer in 1 containing two types of inorganic anions.
• Compound 2 exhibits a rare 5-connected noy topology.
• Compound 2 exhibits luminescent emission with large red-shift of 79 nm.
Two new main group coordination polymers, [Ba3(μ5-H2hmIDC)(μ5-H3hmIDC)(μ4-NO3)2(μ3-Cl)]n (1) and [Pb(μ5-HhmIDC)]n (2), were obtained under hydrothermal conditions. Compound 1 exhibits a 3-dimensional pillar-layer framework, the Cl− and NO3− anions link Ba(II) ions to generate a interesting two-dimensional layer containing two types of inorganic anions, which is further pillared by the H4hmIDC linkers, giving the final three-dimensional pillared-layer networks. Compound 2 is a 3D framework based on 1D secondary building blocks and exhibits a 5-connected noy topology. The thermogravimetric analyses and luminescence properties of compounds 1–2 were also investigated.
Two 3D main group coordination polymers based on 2-(hydroxymethyl)-1H-imidazole-4,5-dicarboxylic acid were constructed. They are 3D pillar-layer and 5-connected framework, respectively. The Pb(II) compound display luminescent emission with large red-shift of 79 nm.Figure optionsDownload as PowerPoint slide
