Two silver(I) coordination solids in a single crystallization: Flexible metallacyclodimer versus helical channel network

Argentophilic Interactions

“…It is important to note that in all these cases the metal atoms are significantly closer to each other than the p-p stacked pyridine rings. [320][321][322] In the large dimetallamacrocycles produced by the coordination of AgO-SO 2 CF 3 or AgPF 6 to a cyclotetraphosphazene bearing pyridinoxy substituents, the folding of the ring depends on the position of the pyridine nitrogen atoms: With 3-pyridinoxy groups, Ag-Ag contacts of 3.199(2) are established across two 20-membered rings, while with 4-pyridinoxy groups the two silver atoms are kept further apart owing to the ligand constraints. Therefore, only an intermolecular contact of 3.408 is established (101).…”

Solvent‐Ratio Dependency of Polymorphism of Silver(I) Complexes Containing 1,2,3‐Tris(Isoniconitoyloxy)Benzene

“…[10][11][12][13] Systematic studies on supramolecular isomerism by the same molecular building blocks will allow us to obtain better insight into the factors influencing the structures and crystal growth of novel crystalline materials. [31][32][33][34][35] For crystalline solids, somewhat metastable synthons with tiny differences in energy can initially crystallize simultaneously as intermediate structures in a batch, and are capable of further nucleating their own growth, giving rise to different crystalline polymorphs. [23][24][25][26][27][28][29][30] On the other hand, polymorphism, which is sometimes compared with supramolecular isomerism, is strictly required in order to obtain at least two different crystalline forms of the same chemical species from a solution in the same batch in which difference often arises from different molecular structures and/or crystal packing modes, growth conditions, and growing processes.…”

Anion influence on structure and photoluminescence properties of silver(I) complexes with naphthalene-2,3-diyl-diisonicotinate

“…template assembly, ion-pair recognition, and anion functionality [11][12][13][14][15][16], since the (counter)anions have many features such as negative charge, size, wide range of geometry, coordinating ability, and solvent-and pH-dependence [7,[17][18][19][20][21][22]. Over the past decade, we have demonstrated significant roles for (counter)anions in the self-assembly and physicochemical properties of numerous coordination compounds [8,19,[23][24][25][26][27][28][29][30]. Recently, we reported anion effects on storage utility in metallacyclodimeric silver(I) complexes with naphthalene-2,3-diyl-dipicolinate containing naphthyl moieties as aromatic walls [31].…”
