A novel copper (II) metallacycle as a building block for the assembly of an extended supramolecular array containing channels and helical chains

Complexation of copper (II) perchlorate with <i>cis,cis</i>-1,3,5-cyclohexanetricarboxylic acid (CTA) and <i>cis,trans</i>-1,3,5-triaminocyclohexane (<i>trans</i>-tach) in the presence of triethylamine leads to the formation of a dinuclear metallacycle; [Cu<sub>2</sub>(<i>trans</i>-tach)<sub>2</sub> (CTA)<sub>2</sub>] · 14H<sub>2</sub>O (<b>1</b>). The crystal structure of <b>1</b> shows an extended hydrogen bonded network comprising linear chains of metallacycles running perpendicular to solvent occupied channels
