摘　　要：在室温条件下合成了2个配合物[Ni(DBTA)(DMF)(H_(2) O)_(4)](1)和[Co(DBTA)(DMF)(H_(2) O)_(4)](2)(D-H_(2)DBTA=D-(+)-二苯甲酰酒石酸,DMF=N,N-二甲基甲酰胺),并通过元素分析、FT-IR光谱、X射线单晶及粉末衍射表征了2个配合物的结构。X射线单晶衍射结果表明,2个配合物同构,属于单斜晶系,P21空间群。配合物由配位键形成零维结构,再通过分子间氢键形成三维网状结构。荧光分析表明当激发波长为280 nm时,配合物1和2具有较强的荧光。尽管2个配合物同构,但表现出不同的磁性质:配合物1主要表现出Ni^(2+)离子间弱的反铁磁相互作用,而配合物2则表现为Co^(2+)离子的磁各向异性以及Co^(2+)离子间强的反铁磁相互作用。Two coordination compounds[Ni(DBTA)(DMF)(H_(2) O)_(4)](1)and[Co(DBTA)(DMF)(H_(2) O)_(4)](2)(D-H_(2) DBTA=(+)-2,3-dibenzoyl-D-tartaric acid,DMF=N,N-dimethylformamide)have been synthesized at room temperature,and characterized by elemental analyses(EA),FT-IR,X-ray single-crystal and powder diffraction analyses.The structural analysis shows that complexes1 and2 are isomorphic.They belong to the monoclinic system with P2_(1) space group and display a zero-dimensional structure constructed from coordination bonds,which is further interlinked to form a three-dimensional network via hydrogen-bonding interactions.Fluorescence measurements indicate that1 and2 can exhibit strong fluorescence using 280 nm as the excitation wavelength.Though1 and2 are isomorphic,they displayed different magnetic properties.Complex1 dominates weak antiferromagnetic couplings between Ni^(2+)cations,while complex2 exhibits the magnetic anisotropy of the Co^(2+)center and antiferromagnetic interactions between the Co^(2+)cations.CCDC:2072164,1;2065592,2.
