An Interpenetrating Coordination Polymer Containing Weak Hydrogen Bonds and Argentophilic Interactions

Abstract

The structure of the coordination polymer [Ni(en)2][Ag(CN)2]2[Ag2(CN)2] (1; en = ethylenediamine) contains 2D (6,3) sheets in which trans-Ni(en)2{Ag(CN)2}2 moieties bridge between zigzag Ag(CN) chains. The sheets are puckered, and show 3-fold 2D → 2D parallel interpenetration. The structure also contains weak N–H···π(CN) and argentophilic Ag···Ag interactions between the 2D sheets.

The Influence of Weak Interactions on Electric Conductivity of Silver Sulfobenzoate Complexes with Two Neutral Ligands

“…The supra-molecular chemistry of the silver(I) coordination polymers represents a dynamic and thriving field which abounds with various supra-molecular forces such as Ag···ligand, Ag···Ag, Ag···π interactions [2][3][4][5][6][7] and various kinds of hydrogen bonds [including X-H···X, X-H···π, C-H···X, X-H···Ag (X = O, N, halogen), C-H···n (n: lone pair electrons) interactions], π···π stacking and anion interactions, although the closed d 10 configuration of silver(I) appears to cancel any inter-metallic bonding. [8][9][10][11][12][13][14][15][16][17][18] Triphenylphosphine (PPh 3 ) is a bulk and soft ligand. A considerable amount of silver compounds containing the PPh 3 ligand were synthesized and characterized.…”

Hydrothermal synthesis and characterization of Zn(II), Cd(II) and Ag(I)-saccharinate complexes containing bis(imidazol) derivatives

“…Adjacent dinuclear units are connected to each other through ligand unsupported weak AgÁ Á ÁAg interactions with an Ag2Á Á ÁAg2 distance of 3.4303(3) Å, which is slightly shorter than twice the van der Waals radii of the Ag atom (3.44 Å). This interaction is known as an argentophilic interaction [51][52][53][54][55][56][57]. Similar to complex 4, there are intermolecular (CÀH)Á Á ÁAg1 and (C@O)Á Á ÁAg1 interactions (Ag1Á Á ÁH27 = 3.105, Ag1Á Á ÁC27 = 3.244(3) Å and …”

“…There are, however, only three examples in the literature of threefold interpenetrated (6,3) nets with silver, viz. catena-[hexakis( 2 -cyano-2 C:N)bis(ethylenediamine-2 N,N 0 )nickeltetrasilver] (Duriska et al, 2006) (Han et al, 2014).…”
