  具有混合的二肟肟赤道配体的无机钴肟：便捷的一锅合成和顺式影响研究：N 3 Co III（dmgH）（dpgH）Py和N 3 Co III（chgH）（dpgH）Py的X射线晶体结构

  摘要：

  一种简单且通用的合成带有混合二肟肟配体XCo（L）（L'）Py，L，L'= dmgH / dpgH和chgH / dpgH的钴肟的途径; 已经描述了X ＝ Cl，Br，NO 2，N 3。这些化合物是首次报道。N 3 Co（dmgH）（dpgH）Py和N 3 Co（chgH）（dpgH）Py的X射线结构证实了合成。已通过1 H-，13 C-NMR研究了这些配合物和XCo（L）2 Py（L = dmgH，chgH，dpgH; X = Cl，Br，NO 2，N 3）配合物的顺式和反式作用，紫外线和X射线。对于一系列X配体，在1 H之间存在明显的趋势，观察到了赤道和轴向配体以及Co-dioxime CT谱带的13 C化学位移。对13 C值和X射线数据的分析表明，在混合的二肟配合物中，一个二肟翅膀会影响另一个二肟翅膀。

  Impact of Ligand Exchange in Hydrogen Production from Cobaloxime-Containing Photocatalytic Systems

  摘要：

  Ligand exchange on the Co(dmgH)(2)(py)Cl water reduction catalyst was explored under photocatalytic conditions. The photosensitizer fluorescein was connected to the catalyst through the axially coordinated pyridine. While this two-component complex produces H(2) from water under visible light irradiation in the presence of triethanolamine (TEOA), it is less active than a system containing separate fluorescein and [Co(III)(dmgH)(2)(py)Cl] components. NMR and photolysis experiments show that the Co catalyst undergoes pyridine exchange. Interestingly, glyoximate ligand exchange was also observed photocatalytically and by NMR spectroscopy, thereby showing that integrated systems in which the photosensitizer is linked directly to the Co(dmgH)(2)(py)Cl catalyst may not remain intact during H(2) photogeneration. These studies have also given rise to insights into the catalyst decomposition mechanism.

  A simple and general route to the synthesis of organocobaloxime with mixed dioxime ligands, RCo(L)(dpgH)Py [L = dmgH and chgH] (R = Me-Dec), has been described. The crystal structure of four complexes, ClCo(L)(dpgH)Py and MeCo(L)(dpgH)Py [L = dmgH and chgH], is reported. The structural study reveals that both the nonclassical C−H···O as well as the classical O−H···O intermolecular hydrogen bonding

  已经描述了一种简单且通用的合成带有混合二氧肟配体RCo（L）（dpgH）Py [L = dmgH和chgH]（R = Me-Dec）的有机钴肟的途径。报道了四种配合物ClCo（L）（dpgH）Py和MeCo（L）（dpgH）Py [L = dmgH and chgH]的晶体结构。结构研究表明，既存在非经典CHH··O，也存在经典OHH···O分子间氢键，并导致一维二聚或聚合物结构的形成。轴向吡啶配体中的1 H和13 C NMR配位位移显示与赤道配体的化学位移具有明显的相关性。这些相关性可以借助振铃电流模型来合理化。

  A simple and general route to the synthesis of organocobaloxime with mixed dioxime ligands, RCo(dmgH)(dpgH)Py and RCo(chgH)(dpgH)Py, has been described. The C-13-NMR chemical shifts have been analysed to see whether one dioxime wing has any effect on the other dioxime wing. The first crystal structure of an organocobaloxime with mixed dioxime ligand in the same complex, BnCo(dmgH)(dpgH)Py and BnCo(chgH)(dpgH)Py, is reported. (C) 2001 Published by Elsevier Science B.V.
