中文摘要	In our efforts to investigate the factors that affect the formation of coordination architectures, such as secondary coordination donors and pendant skeletons of the carboxylic acid ligands, as well as H-bonding and other weak interactions, two kinds of ligands: (a) 3-(2-pyridyl)pyrazole (L-1) with a non-coordinated N atom as a H-bonding donor, a 2,2'-bipyridyl-like chelating ligand, and (b) four carboxylic ligands with different secondary coordination donors and/or pendant skeletons, 1,4-benzenedicarboxylic acid (H2L2), 4-sulfobenzoic acid (H2L3), quinoline-4-carboxylic acid (HL4) and fumaric acid (H2L5), have been selected to react with Mn(II) salts, and five new complexes, [Mn(L-1)(2)(SO4)](2) (1), [Mn(L-1)(2)(L-2)]infinity (2), [Mn(L-1)(HL3)(2)]infinity (3), Mn(L-1)(2)(L-4)(2) (4), and [Mn(L-1)(2)(L-5)]infinity (5), have been obtained and structurally characterized. The structural differences of 1-5 can be attributed to the introduction of the different carboxylic acid ligands (H2L2, H2L3, HL4, and H2L5) with different secondary coordination donors and pendant skeletons, respectively. This result also reveals that the typical H-bonding (i.e. N-H center dot center dot center dot O and O-H center dot center dot center dot O) and some other intra- or inter-molecular weak interactions, such as C-H center dot center dot center dot O weak H-bonding and pi...pi interactions, often play important roles in the formation of supramolecular aggregates, especially in the aspect of linking the multi-nuclear discrete subunits or low-dimensional entities into high-dimensional supramolecular networks.
