isolated from the reaction of CuX with 1 equiv of the phosphine ligand. Most of them have been characterized by X-ray diffraction studies in the solid state, thus allowing comparative discussions of different structural parameters, namely, Cu···Cu and Cu···Aryl separations, conformations adopted by coordinated phosphines, and planarity of the Cu2X2 cores. Centrosymmetric complexes [CuI(PMe2ArXyl2)]2,
几个双核三联苯磷化氢铜(I)的组合物,卤化物配合物[的CuX(PR 2的Ar')] 2(X =氯,溴,I; R =烃基中,Ar'= 2,6- diarylterphenyl自由基),1 - 5,已经从CuX与1当量的膦配体的反应中分离出α-己内酰胺。它们中的大多数已经通过固态X射线衍射研究进行了表征,因此可以比较讨论不同的结构参数,即Cu··Cu和Cu···Aryl分离,配位膦所采用的构象以及Pb的平面度Cu 2 X 2芯。中心对称的配合物[的CuI(PME 2的Ar XYL2)] 2,1C和[碘化亚铜(PET 2的Ar Mes2)] 2,3C,尽管它们相似的结构,示出了粉末形式的非常明显的光致发光(PL)在室温下。DFT计算已经研究并支持了这些化合物在液体溶液,固-固Zeonex溶液和粉末样品在室温和77 K下的光物理行为。通过群论计算和投影算子技术对振动耦合模态的识别表明,这些模态的表
