[N-(3-Aminopropyl)-N-methyl-1,3-propanediamine-κ³N]dichlorocopper(II)

The preparation and crystal structure of the title complex, [CuCl₂(C₇H₁₉N₃)], are described. The Cu^II ion has distorted tetragonal pyramidal geometry, with Cl axial; the axial Cu—Cl distance [2.505 (1) Å] is elongated compared with the basal Cu—Cl distance [2.400 (1) Å]. In the basal plane, Cu—N(tertiary) [2.138 (3) Å] is considerably longer than Cu—N(primary) [1.985 (4) Å mean], presumably reflecting the reduced basicity of the ligand atom.
