摘要：

Two polymeric complexes, [Cu-2(btec)(phen)(2)](n).(H2O)(n) (1) and [Cd-4(btec)(2)(phen)(4)(H2O)(4)](n) (2) (H(4)btec = 1,2,4,5-benzenetetracarboxylic acid, phen = 1,10-phenanthroline), were synthesized by solvothermal reactions at 140 degreesC. Both complex 1 and 2 possess infinite double-chain structures, in which each Cu(II) center has a tetrahedral configuration and the Cd(II) centers adopt triangular prismatic and square-based pyramidal configurations simultaneously. The inter-chain face to face pi-pi interactions among the aromatic rings of phen and the hydrogen bond interactions between aqua molecules and carboxyl 0 atoms result in 3-D networks in the two complexes. The ESR spectra study of complex 1 shows that there is negligibly small long-range super-exchange interactions between the Cu(II) atoms via benzenecarboxylate bridging. (C) 2001 Elsevier Science Ltd.
