摘要：

The reaction of Cd(NO3)(2) with 5-sulfoisophthalic acid monosodium salt (NaH(2)sip) in the presence of piperazine (pip) or ethylenediamine (en) produced three-dimensional supramolecular complexes [Cd(sip)(Hpip)(H2O)(2)] (1) and [Cd(sip)(H2O)(3)] center dot 0.5 (H(2)en) center dot H2O (2). In both compounds, the Cd2+ atoms are linked by sip(3-) into a one-dimensional zig zag chain. The resultant negative ribbons are charge balanced by the coordinated protonated pip (Hpip) in 1 but by free, half occupied H(2)en in 2. The zigzag chains are further linked together by hydrogen bonds and pi-pi stacking interactions to form supramolecular open frameworks. Both 1 and 2 show violet blue photoluminescence at room temperature. (c) 2005 Elsevier B.V. All rights reserved.
