14-hexamethyl-1,4,8,11-tetraazacyclotetradecane. The crystal structures of 1 and 2 were determined by single-crystal X-ray analysis. The NiII ion is pseudooctahedrally coordinated. The coordination geometry around the CuII ion in 2 is slightly distorted square planar, while that in 1 shows significant distortion towards a tetrahedral structure. The temperature dependence of the magnetic susceptibility
