水热合成了3个锰Ⅱ配位超分子配合物[Mn（pdc）（H2O）]n1，{[Mn（pdc）（phen）（H2O）]·3 H2O}n2和{[Mn（cyan）2（H2O）4]·2 HCl·2（Hcyan）} 3（H2 pdc =吡啶-2，3-二甲酸，Hcyan =氰尿酸，phen = 1，10-邻菲咯啉），并通过单晶X射线衍射对其结构进行了表征.络合物1中的pdc基团桥接MnII离子以形成无限的3D结构。在配合物2中，MnII离子通过pdc基团桥连到一维无限链上，并且该链通过氢键进一步连接到二维结构上。配合物3的三维结构由氢键和O···Cl弱相互作用形成。配合物1-3的表面光电压谱（SPS）表明它们在300-800 nm范围内都具有正的SPV响应，表现出p型半导体特性。SPV响应的强度明显不同，这主要归因于它们的结构差异。配合物1-3的场诱导表面光电压谱（FISPS）证实了它们的p型半导体特性。（© Wiley-VCH Verlag GmbH & Co.

Three MnII coordination supramolecular complexes [Mn(pdc)(H2O)]n1, {[Mn(pdc) (phen)(H2O)]·3H2O}n2, and {[Mn(cyan)2(H2O)4]·2HCl·2(Hcyan)} 3 (H2pdc = pyridine-2,3-dicarboxylic acid, Hcyan = cyanuric acid, phen = 1,10-phenanthroline) were hydrothermally synthesized and their structures determined by single-crystal X-ray diffraction. The pdc group in complex 1 bridges the MnII ions to form an infinite 3D structure. In complex 2, the MnII ion is bridged to a 1D infinite chain by pdc groups and the chain is further connected to a 2D structure by hydrogen bonds. The 3D structure of complex 3 is formed by hydrogen bonds and O···Cl weak interactions. Surface photovoltage spectroscopy (SPS) of complexes 1–3 indicate that they all possess positive SPV response in the range of 300–800 nm and show p-type semiconductor characteristic. The intensities of the SPV responses are obviously different, and this can mainly be attributed to the differences in their structures. Field-induced surface photovoltage spectroscopy (FISPS) of complexes 1–3 confirms their p-type semiconductor characteristic.(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
