Bridged Silver(I) Complexes of the Polycyclic Aromatic Compounds Tetraphenylethylene and 1,1,4,4-Tetraphenyl-1,3-butadiene

For the purpose of investigating the coordination behavior of the sterically congested alkenes and exploring the
possibility of cofacial complexation in the polycyclic aromatic system for formation of extended polymeric networks,
tetraphenylethylene (tphe) and 1,1,4,4-tetraphenyl-1,3-butadiene (tphb) have been studied with regard to their
complexation with a silver(I) ion. The crystal structures of [Ag(tphe)(ClO4)(p-xylene)], [Ag2(tphe)(ClO4)2],
[Ag4(tphe)(CF3SO3)4], [Ag2(tphb)(ClO4)2], and [Ag2(tphb)(CF3SO3)2], together with the metal-free ligands tphe
and tphb, have been determined by single-crystal X-ray diffraction. The π-electron-rich cleft in organic components
is found to offer a potential site for complexation, which can be utilized to generate an interesting array of
organometallic compounds with one- and two-dimensional frameworks.

为探究空间位阻烯烃的配位行为，以及探索多环芳烃体系中通过面对面络合形成延伸聚合物网络的可能性，研究人员针对四苯乙烯（tetraphenylethylene, tphe）与1,1,4,4-四苯基-1,3-丁二烯（1,1,4,4-tetraphenyl-1,3-butadiene, tphb）与银(I)离子的络合作用展开了研究。通过单晶X射线衍射，测定了配合物[Ag(tphe)(ClO₄)(对二甲苯)]、[Ag₂(tphe)(ClO₄)₂]、[Ag₄(tphe)(CF₃SO₃)₄]、[Ag₂(tphb)(ClO₄)₂]、[Ag₂(tphb)(CF₃SO₃)₂]，以及无金属配体tphe和tphb的晶体结构。研究表明，有机组分中富含π电子的裂隙可作为潜在的配位位点，借此可构建一系列具有一维及二维骨架的有机金属化合物。
