Abstract

Reaction of bis(pentafluorophenyl)mercury (1) with the Pd(II) complexes [Pd(salophen)] (I, salophen = N,N'-disalicylidene-o-phenylenediaminate) and [Pd(N--C)(OAc)]2 (II, N--C = (2-(2-pyridyl)phenyl-C,N)) leads to the formation of the supramolecular complexes [1-(I)2] and [1-(II)2] in which the mercury synthon is sandwiched by two molecules of the palladium complex. These complexes, whose formation can be observed in solution by UV-vis spectroscopy, have been fully characterized. The short Hg-Pd distances of 3.2841(2) A in [1-(I)2] and 3.1065(8) A in [1-(II)2] indicate the presence of a Hg-Pd metallophilic interaction which, at least for [1-(II)2], is complemented by a Pd(II)-->Hg(II) donor-or component.

摘要

双（五氟苯基）汞（1）与钯（II）配合物[Pd（salophen）]（I，salophen = N，N'-二水杨醛缩邻苯二胺）和[Pd（N^C）（OAc）]2（II，N^C = （2-（2-吡啶基）苯基-C，N））反应生成超分子配合物[1·（I）2]和[1·（II）2]，其中汞合成子夹在两个钯配合物分子之间。这些配合物的形成可通过紫外可见光谱在溶液中观察到，并已得到充分表征。[1·（I）2]中Hg-Pd的短距离为3.2841（2）Å，[1·（II）2]中为3.1065（8）Å，表明存在Hg-Pd亲金属相互作用，至少对于[1·（II）2]，这种相互作用由Pd（II）→Hg（II）供体-受体组分补充。
