  Stepwise Formation of Molecular Rectangles of Half-Sandwich Rhodium and Ruthenium Complexes Containing Bridging Chloranilate Ligands

  摘要：

  Binuclear complexes [Cp*Rh-2(2)(mu-CA)Cl-2] (2a) and [(p-cymene)(2)Ru-2(mu-CA)Cl-2] (2b) (CA = chloranilate) were obtained by the reactions of [Cp*RhCl(mu-Cl)](2) (1a) or [(p-cymene)RuCl(mu-Cl)](2) (1b) with H(2)CA in the presence of base, respectively. Treatment of 2a or 2b with bidentate ligands (L) such as pyrazine, 4,4'-dipyridine (bpy), 2,5-bis(4-pyridyl)-1,3,5-oxadiazole (bpo), and E-1,2-bis(4-pyridyl)ethene (bpe) in the presence of AgOTf (OTf = CF3SO3) in CH3OH gave the corresponding tetranuclear complexes, with the general formulas [Cp*Rh-4(4)(mu-CA)(2)(mu-L)2](OTf)4 (3a-d) and [(p-eymene)(4)Ru-4(u-CA)(2)(mu-L)(2)](OTf)(4) (4a-d), respectively. The molecular structures Of [Cp*Rh-4(4)(mu-CA)(2)(mu-bpy)(2)](OTf)(4) (3b), [(p-cymene)(4)Ru-4(mu-CA)(2)(mu-bPY)(2)](OTf)(4) (4b), and [(p-cymene)(4)Ru-4(mu-CA)(2)(mu-bPe)(2)](OTf)(4) (4d) have been determined by single-crystal X-ray analysis and revealed that the metal centers were connected by pyridyl ligands and bis-bidentate chloranilate (CA) ligands to construct a rectangular cavity with different dimensions and strong pi interactions between independent molecules to form rectangle channels in the solid state.

  The coordinatively unsaturated 16-electron half-sandwich precursors [Cp*M(pdt)] (M = Rh and Ir, pdt = pyrazine-2,3-dithiol) have been synthesized. Their bridging and unsaturated attributes are further used in stepwise assembly reactions with binuclear blocks to give a closed molecular box.

  and synthesis of mixed‐metal coordination cages, which can act as hosts to encapsule guest molecules, is a subject of intensive research, and the utilization of metalloligand is an effective method to construct a designed heterometallic architecture. Herein, a series of heterometallic cages with half‐sandwich Rh, Ir and Ru fragments using CuII‐metalloligand as a building block by a stepwise approach

  可以充当胶囊客体分子宿主的混合金属配位笼的设计与合成是一项深入研究的课题，金属配体的利用是构建设计的异金属结构的有效方法。在本文中，报道了一系列使用Cu II-金属配体作为分步结构的，具有半夹心Rh，Ir和Ru片段的杂金属笼。笼子的空腔大小可以通过有机配体的长度容易地控制。由于草酸盐基笼中的金属配体有些扭曲且呈凹形，因此分子中的Cu⋅⋅⋅O相互作用较弱，形成了双核铜单元。通过使用较长的配体2,5-二氯-3,6-二羟基-1,4-苯醌（H 2CA），有机金属盒显示出有趣的宿主-客体行为，这种行为足够大以容纳一些大分子，例如pyr和[Pt（acac）2 ]。有趣的是，在吡嗪存在下，具有较大腔体尺寸的杂金属笼可以转移到均金属六核棱柱体中。

  Tetranuclear half-sandwich iridium or rhodium complexes were obtained in good yields from the reactions of the binuclear half-sandwich metal precursors [Cp*M-2(2)(mu-CA)]Cl-2 (1a, M = Ir; 1b, M = Rh; CA = chloranilate) or [Cp*M-2(2)(mu-DHNA)]Cl-2 (2a, M = Ir; 2b, M = Rh; H(2)DHNA = 6,11-dihydroxynaphthacene-5,12-dione) with diPyNI (diPyNI = N,N-bis(4-pyridyl)-1,4,5,8-naphthalenetetracarboxydiimide) in the presence of AgOTf (OTf = CF3SO3) in CH3OH, respectively. The new metallarectangles have been characterized by elemental analysis, FT-IR, H-1 NMR, electrospray mass spectrometry (ESI-MS), and UV/vis absorption spectroscopy. The interactions of these metallarectangles with aromatic molecules, especially pyrene, in solution have been studied by various NMR techniques (1D, DOSY, and ROESY) and UV-vis absorption. DOSY measurements suggest that the interactions between metallarectangle 4a and pyrene are outside of the cavity. The strong pi center dot center dot center dot pi interactions between pyrene and the naphthalenetetracarboxydiimide ring of metallarectangle 4a were further supported by single-crystal X-ray diffraction data; pyrene molecules are found outside the cavity of the metallarectangle.
