Five new binuclear lanthanide compounds [Ln(2,4-DClBA)3phen]2(Ln = Pr(1), Eu(2), Tb(3), Ho(4) and Er(5); 2,4-DClBA = 2,4-dichlorobenzoate; phen = 1,10-phenanthroline) have been synthesized and structurally characterized by X-ray crystallography. And all of them were carefully investigated by elemental analysis, molar conductance, IR, UV and TG/DSC-FTIR technology. Single-crystal X-ray diffraction studies revealed that compounds 1–5 were binuclear molecules with an inversion center and the Ln3+ ions contained two kinds of coordination environment that was a distorted monocapped square-antiprism in the compounds 1–2, and a distorted square-antiprism geometry in the compounds 3–5. The 3D surface graphs for the FTIR spectra of gaseous products for the compounds 1–5 were recorded using simultaneous TG/DSC-FTIR technique which is intended to further analysis of the thermal decomposition processes. Hence the gaseous products were identified by the solved single IR spectra obtained at different temperatures from the 3D surface graphs. Furthermore, the Eu(Ш) and Tb(Ш) ternary compounds exhibited intense luminescence under the radiation of UV light. And the results for antimicrobial test show that these compounds exhibit good bacteriostatic activity against Staphylococcus aureus, and better antimicrobial activity against Escherichia coli and Candida albicans.

采用常温溶液挥发法,以D-(-)-/L-(+)-对羟基苯甘氨酸(D-/L-Hhpg)为主配体,2种含氮吡啶配体4,4'-联吡啶(4,4'-bipy)和5,5'-二甲基-2,2'-联吡啶(5,5'-BM-2,2'-bipy)为辅助配体,与Co Cl_(2)·6H_(2)O反应合成了2对手性配合物{[Co(D-hpg)(4,4'-bipy)(H_(2)O)]Cl·H_(2)O}_(n )(1-D)、{[Co(L-hpg)(4,4'-bipy)(H_(2)O)]Cl·H_(2)O}_(n )(1-L)、[Co(D-hpg)_(2)(5,5'-BM-2,2'-bipy)]Cl·5.5H_(2)O (2-D)、[Co(L-hpg)_(2)(5,5'-BM-2,2'-bipy)]Cl·5.5H_(2)O (2-L)。通过单晶X射线衍射、元素分析、红外光谱、粉末X射线衍射等多种测试方法对其结构进行分析和表征。配合物的单晶X射线衍射数据表明,配合物1-D和1-L属于单斜晶系,P2_(1)手性空间群,分别呈现1D左手螺旋链和右手螺旋链,通过4,4'-bipy分子扩展为2D网状矩形格子结构。配合物2-D属于单斜晶系,P2_(1)手性空间群,为0D小分子,在氢键的作用下形成1D超分子双链,并以ABAB形式在a轴方向堆积排布。这些配合物的结构差异归因于辅助配体和Hhpg配位模式的影响。此外,还研究了配合物的电化学性质。配合物1-D表现出电化学可逆的氧化还原行为,并可作为电化学传感器用于有效地检测组氨酸对映体和定量测定组氨酸混合物中的对映体过量。
