catena-Poly[bis[silver(I)-μ₂-4,4′-bipyridine-κ²N:N′] naphthalene-2,6-dicarboxylate tetrahydrate]: self-assembly of a supramolecular frameworkviacoordination bonds and supramolecular interactions

Abstract

The ultrasonic reaction of AgNO(3), 4,4'-bipyridine (bipy) and naphthalene-2,6-dicarboxylic acid (H(2)NDC) gives rise to the title compound, {[Ag(2)(C(10)H(8)N(2))(2)](C(12)H(6)O(4)).4H(2)O}(n). The NDC dianion is located on an inversion centre. The Ag(I) centre is coordinated in a linear manner by two N atoms from two bipy ligands. The crystal structure consists of one-dimensional Ag(I)-bipy cationic chains and two-dimensional NDC-H(2)O anionic sheets, constructed by coordination bonds and supramolecular interactions, respectively.

Encapsulated Diverse Water Aggregates in Two Ag(I)/4,4′-Bipyridine/Dicarboxylate Hosts: 1D Water Tape and Chain

“…In our previous work on the Ag(I)/bipy/aryl-dicarboxylate system, we only obtained some mixed H 2 O − dicarboxylate anionic sheets instead of pure water aggregates. Herein, we replaced aryl − dicarboxylates by aliphatic − dicarboxylates in the above system and obtained two CPs, namely, [Ag 2 (bipy) 2 (ox)·7H 2 O] n ( 1 ) and [Ag 2 (bipy) 2 (adip)·6H 2 O] n ( 2 ) (bipy = 4,4′ - bipyridine, H 2 ox = oxalic acid, H 2 adip = adipic acid) (Scheme ), which incorporate two different water aggregates (1D T7(2) water tape + 1D C4 water chain for 1 and 1D C6 water chain for 2 ).…”

A novel 3D silver(I) supramolecular framework assembled from hybrid ligands incorporating Ag···C interactions

“…As we known, both N-donor heterocyclic ligands such as pyridyl, pyrimidyl, and pyrazinyl ligands and O-donor ligands such as di-, tri-, tetra-carboxylates are excellent synthons for the rational design of coordination polymers [23][24][25][26][27][28][29][30][31][32][33][34], so as a continuation of our research on silver/2-aminopyrimidine/dicarboxylates system, we focus on the silver/H 2 npd/2-aminopyrimidyl derivative system, and successfully obtained a novel 3D supramolecular framework constructed from 1D Ag-npd chains via AgÁÁÁC npd (g 2 ), hydrogen bonds and pÁÁÁp interactions.…”

The solid-state structures of two photoluminescent 2D silver(I) arenedisulfonate incorporating aminopyrimidyl ligands: Substituents influence on π⋯π interaction

“…Although Ag(I) ion is a particularly good candidate for the flexible coordinative tendencies of sulfonate anion, there is limited structures about arenedisulfonate complexes involving the Ag(I) ion and such complexes modified by N-donor ligands [16,17]. On the other hand, 2-aminopyrimidine-type ligands possessing potential hydrogen bond and p-electron donors usually form diverse nonvalent interactions such as hydrogen-bonding, pÁ Á Áp stacking, C-HÁ Á Áp and anionÁ Á Áp interactions [18][19][20][21], and are widely used in designing coordination polymers (CPs) by us [22][23][24][25][26][27][28][29] and others [30,31]. As extended work, we introduced 1,5-naphthalenedisulfonic acid (H2nds) as an auxiliary ligand into our previous systems and successfully obtained two new 2D CPs, namely [Ag(apym)(nds) 0.5 ] n (1) and [Ag(dmapym)(nds) 0.5 ] n (2) (apym = 2-aminopyrimidine, dmapym = 2-amino-4,6-dimethylpyrimidine, H2nds = 1,5-naphthalenedisulfonic acid).…”
