Abstract

Six new calcium metal-organic frameworks [Ca(BDC)(DMF)(H₂O)] (1), [Ca(ABDC)(DMF)] (2), [Ca₃(BTC)₂(DMF) ₂(H₂O)₂]•3H₂O (3), [Ca(H ₂dhtp)(DMF)] (4), [Ca(H₂dhtp)(DMF)₂] (5), and one modification of [Ca(H₂dhtp)₂(H₂O) ₂] (6), (DMF = N,N-dimethylformamide; BDC = 1,4-benzenedicarboxylate anion; ABDC = 2-aminobenzene-1,4-dicarboxylate anion; BTC = 1,3,5- benzenetricarboxylate anion; H₂dhtp = 2,5-dihydroxyterephthalate anion) were synthesized from calcium ions and aromatic carboxylic acids by solvothermal reactions and microwave-assisted solvothermal reactions. The single crystal structure analysis showed that all complexes display three-dimensional structures containing various inorganic motifs with helical or straight one-dimensional inorganic chains (1-3), pentagonal bipyramidal dimers (4 and 6), or discrete octahedra (5) connected through organic linkers and forming DMF- or water-coordinated neutral frameworks. It is also interesting that compounds 1-5 undergo dissolution/reorganization reactions comprising a break and reformation of the Ca-O bond and leading to destruction/construction structural transformations. Compounds 1-5 were further characterized by thermal gravimetric analysis, powder X-ray diffraction, UV-vis, infrared, and PL spectroscopy.
