    带有强供体六氢嘧啶基配体的铼(I)羰基配合物的电子特性
    摘要:
    Re(I) 三羰基配合物是使用双齿和三齿配体合成的,配体配有一个或两个六氢嘧啶并嘧啶 (hpp) 单元,连接到吡啶或吡嗪环。这些配合物已通过 NMR、ESI-MS、振动和光学光谱以及电化学进行表征。它们的结构是通过单晶 X 射线晶体学确定的,并使用 DFT 和 TD-DFT 方法进行建模。该配合物在室温下在溶液中不发光,但在 77 K 时显示出具有混合内部配体(主要)和金属-配体(次要)电荷转移特征的发光。此外,两种基于吡嗪的配合物在固态下似乎都是发光的,大概是由于在晶体结构中观察到的分子间相互作用的存在。

  • A Facile Route to Substituted Bidentate and Tridentate Ligands Capable of Forming Six-membered Chelate Rings with Transition-Metal Ions

    A facile one-pot synthesis of mono(hpp)- or di(hpp)-substituted N -heterocyclic ligands from halogenated N -heterocycles and 1,3,4,6,7,8-hexahydro-2 H -pyrimido[1,2- a ]pyrimidine (H-hpp) is presented. N , N -Bidentate and N , N , N -tridentate ligands incorporating electron-donating and electron-withdrawing substituents can also be readily synthesized using this method.

    A new class of cationic iridium(iii) complexes of the form [(CN)2Ir(NN)][PF6] is reported, where CN = cyclometallating 2-phenylpyridinato, ppy, or 2-(2,4-difluorophenyl)-5′-methylpyridinato, dFMeppy, and NN = guanidyl-pyridine, gpy, or -pyrazine, gpz, as the ancillary ligand.

    The synthesis and characterization of a novel family of [Ru-II(bpy)(2)(N-N)](PF6)(2) (bpy = 2,2'-bypyridine) complexes are reported, where N-N = pyridine/pyrimidine/pyrazine functionalized in different positions with the electron-donating bicyclic hexahydropyrimidopyrimidine (hpp) unit. A series of bidentate ligands 1a-5a were synthesized in good to high yields (55-96%). The corresponding complexes 1b, 2b, and 5b were prepared in n-butanol, while complexes 3b and 4b were prepared in a mixture of n-butanol and water (1/1, v/v) in modest to good yields (23-76%). Both ligand and complex structures were fully characterized by a variety of techniques, including X-ray crystallography. In cyclic voltammetric studies, all the complexes exhibit a Ru-III/II couple, which is similar to 500 mV less positive than the Ru-III/II couple in Ru(bpy)(3)(2+). The (MLCT)-M-1 and (MLCT)-M-3 states of all of the complexes (530-560 nm/732-745 nm) are shifted bathochromically in comparison to those of Ru(bpy)(3)(2+) (450 nm/620 nm). These values are in good agreement with DFT and TD-DFT calculations.
  • Electronic Properties of Rhenium(I) Carbonyl Complexes Bearing Strongly Donating Hexahydro‐Pyrimidopyrimidine Based Ligands

    Re(I) tricarbonyl complexes have been synthesized using bi- and tridentate ligands equipped with one or two hexahydro-pyrimidopyrimidine (hpp) units attached to either a pyridine or a pyrazine ring. These complexes have been characterized by NMR, ESI-MS, vibrational and optical spectroscopies as well as electrochemistry. Their structures were determined via single-crystal X-ray crystallography and
