Crystal structure of {(but-3-en-1-yl)bis­(pyridin-2-yl)meth­ylamine-κ3NN′N′′}di­chlorido­copper(II) diethyl ether hemisolvate

摘要

The five-coordinate Cu^II atom in the title complex [CuCl2(C16H19N3)]·0.5C4H10O, adopts a near-ideal square-pyramidal geometry (τ-5 = 0.01). The apical Cu—Cl distance is 0.2626 (6) Å longer than the basal Cu—Cl distance. Weak C—H⋯Cl interactions between pyridine rings and the Cl atoms of adjacent complex molecules are present. The solvent molecule, located on a twofold rotation axis, is situated in the voids of this arrangement. Copper atoms coordinated by tridentate nitro­gen-containing ligands have been found to be excellent promoters of Atom Transfer Radical Addition (ATRA) reactions.
