Abstract

The five-coordinate CuII 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.
