中文摘要	Three new 4-cyanobenzoate coordination complexes have been prepared, and their structures have been characterized by single-crystal X-ray diffraction. In [Cd(4-cba)(2)(py)(2)(H2O)] 1 and [Mn(4-cba)(2)(phen)(H2O)2] 2 (4-Hcba=4-cyanobenzoic acid, py=pyridine, phen = 1 10-phenanthroline), carboxylate groups exhibit chelated bidentate and terminal monodentate coordination modes, respectively, to give discrete mononuclear units, which are linked by hydrogen bonds and face-to-face pi-pi stacking interactions to produce a 2-D supramolecular network. In [Mn(4-cba)(2)(H2O)(2)](n) 3, the Mn(II) atoms are bridged by carboxylate groups of 4-cba ligands in the syn-skew bidentate mode in two directions to form a 2-D grid-like framework with a (4,4) topology, and there also exist hydrogen bonds and face-to-face pi-pi stacking interactions in the layers. Variable-temperature magnetic susceptibility data show the presence of weak antiferromagnetic interactions with theta=-1.13(5) K in 2 and significant antiferromagnetic ordering (T-N = 7.0 K) with theta=-11.40(5) K in 3. The thermogravimetric analyses of the three complexes have also been discussed. (C) 2006 Elsevier B.V. All rights reserved.
