Argentophile Wechselwirkungen

Abstract: Zwischen 1990 und 2000 wuchs in der Goldchemie das Interesse an aurophilen Wechselwirkungen, nachdem man festgestellt hatte, dass diese eine Vielzahl struktureller und anderer physikalischer Eigenschaften von Gold(I)‐Verbindungen nennenswert beeinflussen. Die Aufmerksamkeit, die man diesem kontraintuitiven inter‐ und intramolekularen Typ von Bindung zwischen Metallzentren mit scheinbar abgeschlossener Elektronenschale entgegenbrachte, hat sich schnell auch auf die Chemie des Silbers ausgeweitet. Hunderte von U… Show more

“…[39,40] Phenomenologically,A gRuO 3 thus appearst ob ed istinctly more 2D than SrRu 2 O 6 .T his latter fact should be regarded as the main origin for the salient differences in the physics between thet wo materials under consideration. In both compounds ruthenium is in the valence state of +5 with an S = 3/2 spin configuration, and the underlying (Ru 2 O 6 ) 2À polyoxoanions are of virtually the same geometry.W hereas the strontium oxide developsa ntiferromagnetic (AF) ordering with an extremelyhigh NØel temperature, AgRuO 3 does not develop any long range order at all, although the magnetic exchange coupling appearst ob ee xtremelys trong, even stronger than in the strontium analogue.…”

“…A comparison of the most relevant structural data of comparable type I compounds, in which the Ag atoms similarly have no further contacts to other donor ligands as in 6 , is summarized in Table 2. All compounds have a baggy eight‐membered ring and the Ag ··· Ag contacts range between 2.71 and 2.97 Å showing great flexibility 21…”

“…The Ag ··· Ag contacts are in the range of 2.71 to 2.98 Å, being shorter or larger, respectively, as in metallic silver, whereras Ag ··· Ag contacts in cluster compounds range between 2.92 and 3.13 Å,29 and in metallic silver a value of 2.89 Å is found 19. Quite recently, Schmidbaur published a survey on all kinds of argentophilic interactions 21…”

“…[19] Quite recently, Schmidbaur published a survey on all kinds of argentophilic interactions. [21] As shown in Table 2 the Y-Ag-Z angles are very flexible varying between 157°and 173°and the bending can be inward or outward. Small bite angles of the bridging ligand correspond to a large angle at the silver atom.…”

“…All compounds have a baggy eight-membered ring and the Ag···Ag contacts range between 2.71 and 2.97 Å showing great flexibility. [21] Theoretical studies on type I compounds were undertaken by Pyykkö et al [22] and related compounds were summarized in a review from the same author. [23] According to relativistic effects the attraction is strong for M = Au and less important for M = Cu, Ag.…”
