“…Furthermore, C-meso-L 2 and C-racemic-L 2 of the copper(II) complexes are not substituted by CN -ion even in boiling (> 10 h) acetonitrile-water (1:1) solutions containing excess NaCN; this can attributed to the topologically constrained structure of the macrotricycles. 13,14 The only complex obtained from the solution was found to be the cyano-bridged…”

Two isomers of a new tetraaza macrotricycle 2, 2,4,9,9,11-hexaazamethyl-1,5,8,12-tetraazatricyclo[10.2.2, have been prepared by the reaction of 1-bromo-2-chloroethane with C-meso- 5,5,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane)shows that the complex has distorted square-pyramidal coordination geometry with an apically coordinated water molecule. Unexpectedly, the. The copper(II) complexes readily react with CN -ion to yield the cyano-bridged dinuclear complex [ , respectively.
