%X Reaction of (3,7-dithianonane-1,9-diamine)copper(II) ion with nitroethane and formaldehyde in basic methanol gives the macrocyclic complex ion (6-methyl-6-nitro-1,II-dithia-4,8- diazacyclotetradecane )copper(II) in high yield. The complex as the perchlorate salt crystallizes in the monoclinic space group P21/n, a 15.008(5), b 8.606(3), c 17.967(4)&#506;, &#946; 113.79(2)°. The copper ion lies in a square plane of two nitrogen (average Cu-N 2.02 &#506;) and two thioether (average Cu-S 2.295 &#506;) donors, with perchlorate  oxygens (Cu-O 2.46 and 2.70 &#506;) in axial sites. Physical and structural properties of the CuIII complexes of the 14-membered cis-N2S2 macrocycle and the known analogous 14-membered N4-donor macrocycle 6-methyl-6-nitro-1,4,8,11- tetraazacyclotetradecane are compared.
