A new layered Ca-succinate coordination polymer.
A new layered Ca-succinate coordination polymer, poly[μ(3)-succinato-calcium(II)], [Ca(C(4)H(5)O(4))](n), was synthesized by reaction of CaCl(2)·2H(2)O 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.
