Crystal structure and Hirshfeld surface analysis of one-dimensional copper(II) coordination polymer incorporating succinate and tetra-methyl-ethylene-diamine ligands.

ABSTRACT: The reaction of copper nitrate with succinic acid (succH) and N,N,N',N'-tetra-methyl-ethylenedi-amine (TMEDA) in basic solution produces the complex catena-poly[[[(N,N,N',N'-tetra-methyl-ethylenedi-amine-κ2 N,N')copper(II)]-μ-succinato-κ2 O 1:O 4] tetra-hydrate], {[Cu(C4H4O4)(C6H16N2)]·4H2O} n or {[Cu(succ)(tmeda)]·4H2O} n . Each carboxyl-ate 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 mol-ecules 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 inter-molecular contacts within the supra-molecular structure.
