Abstract :
The reaction of copper nitrate with succinic acid (succH) and N,N,N′,N′-tetramethylethylenediamine (TMEDA) in basic solution produces the complex catena-poly[[(N,N,N′,N′-tetramethylethylenediamine-κ2N,N′)copper(II)]-μ-succinato-κ2O1:O4] tetrahydrate], {[Cu(C4H4O4)(C6H16N2)]·4H2O}n or {[Cu(succ)(tmeda)]·4H2O}n. Each carboxylate group of the succinate ligand coordinates to a CuII atom in a monodentate fashion, giving rise to a distorted square-planar geometry. The succinate ligands bridge the CuII centres, forming one-dimensional polymeric chains. Hydrogen bonds between the ligands and water molecules link these chains into sheets that lie parallel to the ac plane. Hirshfeld surface analysis, dnorm and two-dimensional fingerprint plots were examined to verify the contributions of the different intermolecular contacts within the supramolecular structure.
