摘要：
In the present investigation, synthesis, crystal structure and magnetic properties of an azide-bridged one-dimensional tape-type coordination polymer of copper(II) of composition [Cu-6(II)(N,N-diEten)(2)(mu(1.1)-N-3)(8)(mu(1.1,1)-N-3)(2)(mu(1,3)-N-3)(2)](n) (1) are described, where N,N-diEten is N,N-diethylethylenediamine. Compound 1 is formed on reacting Cu(ClO4)(2)center dot 6H(2)O, the diamine and NaN3 in 1:0.33:2 molar ratio. Compound I crystallizes in monoclinic space group and P2(1)/n crystal system. The structure of 1 reveals that it is a hexacopper(II)-based tape-type 1-D polymer having three types of azide ligands, mu(1.1)-(EO), mu(1,3)-(EE) and mu(1.1.1)-; while and mu(1.1)- and mu(1.1.1)-azide ligands form Cu-6(II) unit, mu(1,3)-azide ligands interlink the Cu-6(II) units to generate one-dimensional network. Variable-temperature and variable-field magnetic properties of 1 have been studied, revealing overall ferromagnetic interaction. The structure/synthesis procedure/magnetic properties of the title compound are compared with closely similar systems. Interestingly, the pattern of azide-bridged network is new considering metallo-azide compounds of not only copper(II) but also of any other metal ions. (C) 2014 Elsevier Ltd. All rights reserved.
