%X Reaction of bis(ethane-1,2-diamine)copper(II) chloride with acetone in the presence of zinc(II) chloride yields m-chloro-trichloro-2K3Cl-(4,6,6-trimethyl-3,7-diazanon-3-ene-1,9-diamine-1K4N,N&cent;,N&cent;&cent;,N&cent;&cent;&cent;)copper(II)zinc(II). This has copper(II) coordinated by the tetradentate triamine monoimine ligand NH2&#8211;(CH2)2&#8211;N=C(CH3)&#8211; CH2&#8211;C(CH3)2&#8211;NH&#8211;(CH2)2&#8211;NH2. The coordination geometry is pyramidally distorted square planar, with trans N&#8211;Cu&#8211;N angles of 167.5(2) and 178.8(2)&#x02DA;, and Cu&#8211;N distances for primary amine 2.001(4) and 2.007(4), secondary amine 2.011(4) and imine 1.988(4) &#197;. One chloride ion of the &#91;ZnCl4&#93;2&#8211; ion is weakly coordinated axially (Cu&#183;&#183;&#183;Cl 2.679(1) &#197;, Cu&#183;&#183;&#183;Cl&#8211;Zn 110.83(6)&#x02DA; with supporting N&#8211;H&#183;&#183;&#183;Cl hydrogen bonds between the two primary amine groups and two further chloride ions of the ZnCl4 2&#8211; ion &#91;C10H24Cl4CuN4Zn, Mr 471.04, orthorhombic, space group Pna21, a 11.418(1), b 15.392(2), c 10.723(2) &#197;, Z 4, R1 = 0.030 for 2039 reflections with I &#62; 2s(I)&#93;.
