Diversified magnetic behaviors of new nickel(ii) and copper(ii) azido coordination polymers templated by diethyl or triethyl amines†
Abstract
The reactions of NiII or CuII ions with N3− anions in the presence of templated diethyl or triethyl amines afford three new azido-bridged coordination polymers, namely, [Ni(N3)2(Deeda)] (1), (DeaH)[Cu3(N3)7] (2), and (TeaH)[Cu4(N3)9] (3), where Deeda, (DeaH)+ and (TeaH)+ represent N,N-diethylethane-1,2-diamine, diethylammonium and triethylammonium, respectively. Magnetic studies revealed that they exhibit metamagnetism, spin glass and canted ferromagnetism, respectively, induced by different coordination modes of the azide ligands.
