摘要
Four structurally diverse complexes, [Cd(dppz)(bdoa)](n) (1), [Zn(dppz)(bdoa)(H(2)O)](n) (2), [Fe(dppz)(2)(b-doa)](n)center dot 2nH(2)O (3), and [Co(2)(dppz)(2)(bdoa)(2)(H(2)O)](n)center dot 3nH(2)O (4), where H(2)bdoa = benzene-1,4-dioxyacetic acid and dppz = dipyrido[3,2-a:2',3'-c]phenazine, have been hydrothermally synthesized. Compounds 1-4 feature chain structures. There exist pi-pi interactions in the structures of 1, 2 and 4. Two neighboring chains of 1 are linked through the pi-pi interactions into a double chain supramolecular structure. The chains of 2 and 4 are further extended by the pi-pi interactions to form 3D and 2D supramolecular structures, respectively. The structural differences among such complexes show that the transition metals have important influences on their structures. The photoluminescent property of complex 2 and the magnetic property of complex 4 have also been investigated. (C) 2010 Elsevier B.V. All rights reserved.
