• A 2D metal-organic framework is presented.
• The crystals were grown by single gel diffusion technique.
• The structure possesses hydrophobic channels.
• Formation of four types of rings.
• Shows intense blue fluorescence.

A novel 2D metal–organic framework poly[aquaitaconatocalcium(II)] with an open framework structure has been successfully grown by single gel diffusion technique. Sodium metasilicate was used for gel preparation. The structure was determined by single crystal X-ray diffraction. The compound crystallizes in monoclinic space group P21/c with hydrophobic 1D channels. The obtained crystals were further characterized by elemental analysis, FT-IR and UV–Visible spectroscopy, powder X-ray diffraction and thermogravimetry. The luminescent property of the complex was also discussed.

Single crystals of a new 2D metal–organic framework poly[aquaitaconatocalcium(II)] with an open framework structure have been grown by single gel diffusion technique. The compound crystallizes in monoclinic crystal system, space group P21/c. Single crystal X-ray diffraction study revealed the polymeric structure of the compound. The 2D polymeric structure results in the formation of four types of rings in the compound. Another interesting characteristic of the structure is the presence of hydrophobic channels. The luminescent property of the complex was also studied.Figure optionsDownload as PowerPoint slide
