摘要：
Reactions of Zn(NO3)(2)center dot 6H(2)O with 1,3,5-tris(imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (titmb) in the presence of 1,4-benzenedicarboxylic acid (1,4-H2BDC) or 1,3-benzenedicarboxylic acid (1,3-H2BDC) under hydrothermal conditions afforded one 1D and one 2D coordination polymers [Zn-3(titmb)(2)(1,4-BDC)(3)(H2O)(6)] (1) and [Zn-2(titmb)(1,3-BDC)(2)(H2O)] (2), respectively. Similar reactions of Zn(NO3)(2)center dot 6H(2)O with 1,3-bis (imidazol-1-ylmethyl)-2,4,6-trimethylbenzene (bitmb) and 1,4-H2BDC gave rise to one 2D coordination polymer [Zn-2(bitmb)(2)(1,4-BDC)(2)] (3). Compound 1 has a 1D linear chain formed from linking 24-membered [Zn-2(titmb)(2)] metallamacrocycles and [Zn(1,4-BDC)(H2O)(2)] units via imidazolyl groups of titmb ligands. Compound 2 has a 2D network assembled from connecting spiral [Zn-n(1,3-BDC)](n) chains with titmb linkers, while compound 3 also has a 2D network formed by linking 24-membered [Zn-2(bitmb)(2)] metallamacrocycles via 1,3-BDC bridges. The ligands titmb and bitmb in compounds 1-3 adopt less-common cis-trans-trans and cis-trans conformations, respectively. Their thermal and photoluminescent properties were also investigated.
