Abstract
Three heterometallic complexes [M(H2O)(n)][Cu3L2(H2O)] (M = Mn2+, Co2+ or Ba2+) and one dinuclear compound (CuDien)(CuL{H2O}) were prepared by interaction of anionic compounds Cu3L22- or CuL2- with the corresponding cations (H4L = 1,9-dicyano-1,9-bis(hydroximino)-3,7-diazanonane-2,8- dione; Dien = 1,5-diamino-3-azapentane). The complexes [M(H2O)(n)][Cu3L2(H2O)] have a polymeric structure, formed via oligomerization of Cu3L22- units and additionally, in the case of the Ba-salt, by binding of Cu3L22- units through Ba2+. Antiferromagnetic interactions occur in all the complexes, while for [Co(H2O)(6)][Cu3L2(H2O)] there is evidence of some ferromagnetic ordering at low temperatures. The values of J are lower in magnitude than for similar, previously reported systems, which is attributed to the electron-withdrawing effect of the ligand cyano groups.
