| Abstract: | A new layered Ca–succinate coordination polymer, polyμ3‐succinato‐calcium(II)], Ca(C4H5O4)]n, was synthesized by reaction of CaCl2·2H2O and succinic acid in an aqueous medium under hydrothermal microwave conditions. The structure contains infinite layers of edge‐sharing calcium pentagonal–bipyramidal polyhedra forming six‐membered rings connected through succinate ligands. Such an assembly of inorganic building units is unique for calcium metal–organic framework‐type structures. Adjacent layers are packed into a final pseudo‐three‐dimensional structure through weak C—H...O hydrogen bonds. |
