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-κ 2 N , N ′)copper(II)]-μ-succinato-κ 2 O 1 : O 4 ] tetrahydrate], {[Cu(C 4 H 4 O 4 )(C 6 H 16 N 2 )]·4H 2 O} n or {[Cu(succ)(tmeda)]·4H 2 O} n . Each carboxylate group of the succinate ligand coordinates to a Cu II atom in a monodentate fashion, giving rise to a distorted square-planar geometry. The succinate ligands bridge the Cu II 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, d norm and two-dimensional fingerprint plots were examined to verify the contributions of the different intermolecular contacts within the supramolecular structure.
