Crystals of a new clathrate [CuII(hmtd)CuI(CN)3]·CH2Cl2 were afforded from a Me2CO-EtOH-CH2Cl2 solution of a macrocyclic complex CuII(hmtd)CuI(CN)3·2 H2O (hmtd = 5,7,7,12,14,14-hexamethyl- 1,4,8,11-tetraazacyclotetradeca- 4,11-diene). It crystallizes in the monoclinic space group P21/n, a = 7.936(5), b = 18.717(4), c = 17.783(6) Å, β = 98.55(4)°, Z = 4, R = 0.0558 for 1 870 reflections. Unprecedentedly, only one of the three nitrogen-ends of a CuI(CN)3 moiety is coordinated to the square-pyramidal Cu(II) center. The guest CH2Cl2 molecules are captured in the channel between the potlid-shaped [CuII(hmtd)CuI(CN)3] molecules.
