Conformational and coordination plasticity in silver(i) cryptates

Anion Effects on the Formation of Silver(I) Complexes with the Flexible Ligand 4,4′‐Bis(1,2,4‐triazol‐1‐ylmethyl)biphenyl

“…[50][51][52][53][54] A CCDC search was conducted and revealed about pentacoordinated 40 silver complexes with Ag-Ag bonds. [55][56][57][58][59] This complex is a good example of high coordinated silver complexes. The Ag-N(triazole) distances fall in the range 2.221-2.227 Å, which are similar to those observed in complex 3, whereas the Ag-N(azide) distances (2.508-2.584 Å) are shorter than those in complex 3.…”

A Rigid Angular Bidentate Ligand for the Design of a New Class of Coordination Polymers Based on Silver(I) Salts – Influence of the Anion on Coordination Assemblies

“…The Ag-O bond lengths are in the range 2.75-2.78(3) Å, which is comparable to those reported for triflate anions bonded to Ag I ions. [43,44] Moreover each Ag I exhibits an argentophilic Ag···Ag interaction (3.15 Å), which is shorter than the van der Waals radii (3.44 Å) but longer than the Ag···Ag distance in silver metal (2.85 Å). [45][46][47] This interaction binds two adjacent 1D coordination polymers to afford an infinite double chain.…”

Migration of 1,3-diazacyclohexane sub-rings in ring-contracted macrocyclic silver(I) complexes

“…Ag(2) was drawn slightly toward Ag(1), with the result that the two-coordination of Ag(2) did not form a straight line; the angle N(24)-Ag(2)-N(31) was 159.1(2)°. The Ag(1)Á Á ÁAg(2) distance was 2.8994(9) Å, which was sufficiently short-comparable with that of metallic contact (2.89 Å) [16,17]to suggest appreciable d 10 Á Á Ád 10 interaction [13,18,19]. Thus, it was concluded that the ability of the contracted ligand to change to the trans-form allowed the formation of the dinuclear silver(I) complex 2.…”
