Abstract Three cadmium(II) coordination compounds, [Cd(pyip)2(CH3COO)2] (1), [Cd(pyip)2(cis-OH)2]·H2O (2) and [Cd(pyip)2(trans-OH)2]·3H2O (3), based on 2-(pyridin-3-yl)-1H-imidazo[4,5-f][1,10]phenanthroline (pyip) have been synthesized by a hydrothermal method and characterized by elemental analysis, IR spectroscopy and single-crystal X-ray diffraction. Compounds 1, 2 and 3 all appear as monomeric entities, which are further assembled into supramolecular networks by hydrogen bonding interactions. The Cd(II) centers in compounds 2 and 3 lie in distinct octahedral environments with the hydroxyl groups in cis- and trans-positions, respectively, leading to the generation of different structures . Photoluminescence studies of compounds 1–3 were also carried out.

三种基于 2-(pyridin-3-yl)-1H-imidazo[4,5-f][1,10] 菲咯啉的新型镉 (II) 配位化合物：合成、结构和发光

摘要 三种镉(II)配位化合物[Cd(pyip)2(CH3COO)2] (1)、[Cd(pyip)2(cis-OH)2]·H2O (2)和[Cd(pyip)2( trans-OH)2]·3H2O(3),基于2-(pyridin-3-yl)-1H-imidazo[4,5-f][1,10]菲咯啉(pyip)已通过水热法合成并通过元素分析、红外光谱和单晶X射线衍射表征。化合物 1、2 和 3 都表现为单体实体，它们通过氢键相互作用进一步组装成超分子网络。化合物 2 和 3 中的 Cd(II) 中心位于不同的八面体环境中，羟基分别位于顺式和反式，导致产生不同的结构。还进行了化合物 1-3 的光致发光研究。
