2-(Dimethylamino)ethanol-κ2N,O][2-(dimethylamino)ethanolato-κ2N,O]iodidocopper(II)

Abstract

The title compound, [Cu(C4H10NO)I(C4H11NO)], was obtained unintentionally as the product of an attempted synthesis of a Cu/Zn mixed-metal complex using zerovalent copper, zinc(II) oxide and ammonium iodide in pure 2-(dimethyl­amino)­ethanol, in air. The mol­ecular complex has no crystallographically imposed symmetry. The coordination geometry around the metal atom is distorted square-pyramidal. The equatorial coordination around copper involves donor atoms of the bidentate chelating 2-(dimethyl­amino)­ethanol ligand and the 2-(dimethyl­amino)­ethano­late group, which are mutually trans to each other, with four approximately equal short Cu—O/N bond distances. The axial Cu—I bond is substanti­ally elongated. Inter­molecular hydrogen-bonding inter­actions involving the –OH group of the neutral 2-(dimethyl­amino)­ethanol ligand to the O atom of the monodeprotonated 2-(dimethyl­amino)­ethano­late group of the mol­ecule related by the n-glide plane, as indicated by the O⋯O distance of 2.482 (12) Å, form chains of mol­ecules propagating along [101].
