Abstract

The syntheses of the tripodal tetraamine ligands 2-(pyridin-2-yl)-N,N-bis(quinolin-2-ylmethyl)ethan-1-amine (DQPEA), N-(pyridin-2-ylmethyl)-2-(quinolin-2-yl)-N-(2-(quinolin-2-yl)ethyl)ethan-1-amine (DQEPMA), 2-(pyridin-2-yl)-N,N-bis(2-(quinolin-2-yl)ethyl)ethan-1-amine (DQEPEA), N,N-bis(pyridin-2-ylmethyl)-2-(quinolin-2-yl)ethan-1-amine (QEDPMA), and 2-(pyridin-2-yl)-N-(2-(pyridin-2-yl)ethyl)-N-(2-(quinolin-2-yl)ethyl)ethan-1-amine (QEDPEA) containing mixed quinolyl and pyridyl moieties are reported, with 2-vinylquinoline being used to attach quinolylethyl arms to the aliphatic N atom. X-ray crystal structures of [(Mn(DQPEA))₂O₂](ClO₄)₂ ⋅ (CH₃CN)₂, [Cu(DQPEA)NCCH₃](ClO₄)₂, [Zn(DQPEA)NCCH₃](ClO₄)₂, [Pd(DQEPEA)Cl]Cl ⋅ 11H₂O are detailed, with four, five, and six-coordination observed. In addition, the dimeric complex [(DPEA)Co(μ-OH)₃Co(DPEA)](ClO₄)₃ ⋅ 0.5H₂O ⋅ MeCN containing the tridentate DPEA ligand formed by N-dealkylation of QEDPEA is reported. Calculations suggest that the very short Co…Co distance of 2.5946(6) Å in this complex is unlikely to be due to a Co-Co bond.

含混合喹啉基和吡啶基配体的三足配体过渡金属配合物的结构变化。

三元四胺配体 2-(吡啶-2-基)-N,N-双(喹啉-2-基甲基)乙-1-胺 (DQPEA) 的合成、N-(吡啶-2-基甲基)-2-(喹啉-2-基)-N-(2-(喹啉-2-基)乙基)乙-1-胺 (DQEPMA)、2-(吡啶-2-基)-N,N-双(2-(喹啉-2-基)乙基)乙-1-胺 (DQEPEA)、N、报告了含有喹啉基和吡啶基混合分子的 2-(吡啶-2-基)-N-(2-(吡啶-2-基)乙基)-N-(2-(喹啉-2-基)乙基)乙-1-胺 (QEDPEA) 和 2-(吡啶-2-基)-N-(2-(吡啶-2-基)乙基)-N-(2-(喹啉-2-基)乙基)乙-1-胺 (QEDPEA)。详细介绍了[(Mn(DQPEA))2O2](ClO4)2 ⋅ (CH3CN)2、[Cu(DQPEA)NCCH3](ClO4)2、[Zn(DQPEA)NCCH3](ClO4)2、[Pd(DQEPEA)Cl]Cl ⋅ 11H2O 的 X 射线晶体结构，观察到四配位、五配位和六配位。此外，还报道了二聚配合物 [(DPEA)Co(μ-OH)3Co(DPEA)](ClO4)3⋅0.5H2O⋅MeCN，其中含有 QEDPEA N-脱烷基化形成的三叉 DPEA 配体。计算表明，该复合物中 2.5946(6)埃的极短 Co...Co 间距不太可能是 Co-Co 键造成的。

期刊介绍： ChemistryOpen is a multidisciplinary, gold-road open-access, international forum for the publication of outstanding Reviews, Full Papers, and Communications from all areas of chemistry and related fields. It is co-owned by 16 continental European Chemical Societies, who have banded together in the alliance called ChemPubSoc Europe for the purpose of publishing high-quality journals in the field of chemistry and its border disciplines. As some of the governments of the countries represented in ChemPubSoc Europe have strongly recommended that the research conducted with their funding is freely accessible for all readers (Open Access), ChemPubSoc Europe was concerned that no journal for which the ethical standards were monitored by a chemical society was available for such papers. ChemistryOpen fills this gap.
