摘要：
A novel cyclic dimer of a trinuclear zinc complex, {[Zn-3(bmtac)(H2O)(8)]center dot 6H(2)O}(2), with very long Zn-Zn distances, was synthesized in aqueous solution by adopting a new type of flexible multicarboxylate ligand, H(6)bmtac (H(6)bmtac = 1,3,5-benzenemethyltriiminodiacetic acid). The X-ray crystal structure of {[Zn-3(bmtac)(H2O)(8)]center dot 6H(2)O](2) reveals that all Zn(II) ions are six-coordinated with octahedral geometry. The dimer as basic building units assembled into a three-dimensional supramolecular framework through the multiple intermolecular O-H center dot center dot center dot O hydrogen bonds interactions. The complex shows a blue fluorescent emission band at 428 nm as the result of the intraligand (pi-pi*) fluorescent emission. (C) 2008 Elsevier B.V. All rights reserved.
