Three-dimensional oxalate-bridged heterometal supramolecular complex with a large helical tunnel of 21.191 x 9.294 angstrom(2)
The preparation, X-ray crystal structure, and magnetic properties of a novel three-dimensional oxalate-bridged heterometal supramolecular complex {K[Cu(trans[14]-dien)]Cr(ox)(3)}(n) (trans[14]dien = 5,7,7,12,14,14-hexamethyl-1,4,8,11 -tetraazacyclotetradeca-4, Il-diene; ox = oxalate ion) have been reported. The magnetic investigation showed that the oxalate-bridged chromium(m)-copper(II) units were antiferromagnetically coupled (J = -9.88 cm(-1)).
