摘要

An octa-azamacrocycle with a 28-membered ring has been found to be capable of incorporating a symmetrical copper-copper bonded unit which contains a short Cu-Cu bond (2.445(4) A). The compound is paramagnetic with mu eff = 1.87 muB at 300 K and exhibits single lines at g = 2.09 in the X-band EPR spectra of solid samples or of frozen acetonitrile solutions (77 K). (Author)
