摘要

trans-Di(cyano-kappa(1))-(trans-6,13-dimethyl-6,13-bis(propionylamicio) -1,4,8,11-tetraazacyclotetradecane-kappa(1))-cobalt(III) perchlorate dihydrate, trans-[Co(C18H38N6O2)(CN)(2))]ClO4 center dot 2H(2)O, is formed by reaction of trans-[Co(diam)(CN)(2)]ClO4 center dot 2H(2)O (diam=trans-6,13-diamino-6,13-dimethyl-1,4,8,11-tetraazacyclotetradecan e) with propionic anhydride in DMF. The centrosymmetrical cation has the azamacrocycle in planar coordination by the four secondary amine nitrogen atoms of the azamacrocycle, with Co-N = 1.979(2) and 1.968(2) angstrom and with trans cyano groups with Co-C = 1.920(2) angstrom. The propionylamido substituents are axially oriented, with the terminal methyl group disordered over two sites. 2008 Elsevier Ltd. All rights reserved.
