[2-(Dimethyl-amino)-ethanol-κ(2)N,O][2-(dimethyl-amino)-ethano-lato-κ(2)N,O]iodidocopper(II)
Abstract:
The title compound, [Cu(C(4)H(10)NO)I(C(4)H(11)NO)], 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-(dimethyl-amino)-ethanol, in air. The mol-ecular 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-(dimethyl-amino)-ethanol ligand and the 2-(dimethyl-amino)-ethano-late group, which are mutually trans to each other, with four approximately equal short Cu-O/N bond distances. The axial Cu-I bond is substanti-ally elongated. Inter-molecular hydrogen-bonding inter-actions involving the -OH group of the neutral 2-(dimethyl-amino)-ethanol ligand to the O atom of the monodeprotonated 2-(dimethyl-amino)-ethano-late group of the mol-ecule related by the n-glide plane, as indicated by the O⋯O distance of 2.482 (12) Å, form chains of mol-ecules propagating along [101].

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
