The behaviour of trans-dihalogenobis(hydrazone)palladium(II) complexes: rotational isomerism or non-equivalence of the two ligands within the same molecule?
A detailed 1H n.m.r. analysis of a series of trans-dihalogenobis(hydrazone)palladium(II) complexes has been made in order to demonstrate unequivocally the presence of tworotationalisomers differing in the mutual orientation of the co-ordinated ligands.
进行了一系列反式-二卤代双(hydr)钯(II)配合物的详细1 H nmr分析,以明确证明存在两个旋转异构体,它们在配位体的相互取向上不同。

4-substituted pyridine co-ligand and the subsequent complexation strength in [2]pseudorotaxane formation. These trends also extended to trans-dibromobis(pyridine)palladium(II) (3a-e) and trans- dichlorobis(pyridine)platinum(II) complexes (5a-e) when plotted against σp° values. In addition, solid-state structures of three [2]pseudorotaxanes (1·2h, 1·2i, and 1·5e) were determined by single crystal X-ray

of [2]pseudorotaxanes, albeit with weaker affinities than the analogous palladium(II) dichloride species. Here, the self-assembly of both [2]rotaxane (2) and [2]catenane (5) were attempted using a PdBr2L2 centre as the template, resulting in the desired interlocked structures. The structures were confirmed by NMR spectroscopy, CSI-MS, and single crystal X-ray diffraction analyses. [2]Rotaxane 2 was
先前的研究已经确定,中性二溴化钯 (II) 络合物是 [2] 假轮烷形成的模板,尽管其亲和力比类似的二氯化钯 (II) 物质弱。在这里,使用 PdBr2L2 中心作为模板尝试了 [2] 轮烷 (2) 和 [2] 链烷 (5) 的自组装,从而产生了所需的互锁结构。通过NMR光谱、CSI-MS和单晶X射线衍射分析证实了结构。[2] 轮烷 2 的分离率为 53%,[2] 链烷 5 的分离率为 41%。与氯化物类似物相比,观察到的产率较低可归因于二溴化钯 (II) 亚基的模板效应降低,这是由间苯二甲酰胺裂隙中溴化物的不良空间配合和溴化物作为氢键受体的能力降低引起的.关键词:

cocrystallizes with a variety of planar aromatic hydrocarbon molecules, the much less soluble complex bis(benzonitrile)palladium(II) dibromide does not act as a source of the so far unknown cluster Pd6Br12. Attempts to prepare the hypothetical bis(benzonitrile)palladium(II) diiodide by reaction of PdI2 with benzonitrile were not successful.

适用于单晶 X 射线衍射研究的平面反式配合物双(苄腈)二氯化钯(II)和双(苄腈)二溴化钯(II)的晶体是通过从苄腈溶液中生长获得的,并确定其结构. 虽然双(苄腈)二氯化钯(II)很容易失去苄腈形成立方簇 Pd6Cl12,它与各种平面芳烃分子共结晶,但溶解度低得多的复合双(苄腈)二溴化钯(II)不作为迄今为止未知的集群 Pd6Br12 的来源。通过 PdI2 与苄腈反应制备假想的双(苄腈)二碘化钯(II)的尝试没有成功。双(苄腈)二氯化钯(II)在对二甲苯中的溶液静置产生 Pd6Cl12·(PhCN)2PdCl2·对二甲苯晶体,
