Two newly designed complexes,[Cu(L1)(H2O)] (1) and [Co3(L2)2(μ2-OAc)2(MeOH)2]· 3CH2Cl2 (2) derived from tetradentate Salamo-type chelating ligands (H2L1 and H2L2) have been synthesized and characterized by elemental analyses,IR and UV-Vis spectra,fluorescence spectra and X-ray crystallography.Complex 1 shows a slightly distorted tetragonal pyramid,forming a dimer supramolecular structure by intermolecular hydrogen bond interactions.While all of the Co(Ⅱ) ions in complex 2 are hexa-coordinated with slightly distorted octahedral coordination geometries.The supramolecular structure of complex 2 is formed via intermolecular hydrogen bond interactions leading to a self-assembly infinite 1D chain structure.The fluorescent properties of H2L1 and H2L2 have been discussed and the crystal structures of complexes 1 and 2 were confirmed by fluorescence titration experiments.CCDC:1561039,1;1561040,2.%合成了2个通过不同的Salamo型香豆素类配体H2L1和H2L2构筑的配合物,[Cu(Ll)(H2O)](1)和[Co3(L2)2(μ2-OAc)2(MeOH)2]·3CH2Cl2(2),并通过元素分析、红外光谱、紫外-可见吸收光谱、荧光光谱以及X射线单晶衍射法对其进行了表征.配合物1中配位的铜(Ⅱ)离子的空间构型是扭曲的四方锥,并且配合物1通过分子间的氢键作用形成了二聚体.配合物2中所有配位的钴(Ⅱ)离子的配位数均为六,并且3个钴(Ⅱ)离子的配位空间构型均为扭曲的八面体同时,配合物2通过分子间的氢键作用形成了一维的超分子链状结构.此外,还分别对配体H2L1和H2L2的荧光性质进行了研究,并且通过荧光滴定实验进一步验证了配合物1和2的晶体结构.
