“…The assignments for the NH 3 bands in [Ag(NH 3 ) 2 ] + [Ag 3 (N 5 ) 4 ]ˉ are unequivocal, including the different N-H stretching vibrations in the region of 3000–3400 cm −1 , the symmetric deformation around 1601 cm −1 , and the rocking mode around 688 cm −1 . These absorptions of [Ag(NH 3 ) 2 ] + in [Ag(NH 3 ) 2 ] + [Ag 3 (N 5 ) 4 ]ˉ agree with those of other diamine silver complexes, such as [Ag(NH 3 ) 2 ]NO 3 and [Ag(NH 3 ) 2 ] 2 SO 4 25,26 . In the infrared spectrum of the AgN 5 complex one additional unassigned band is observed at 1704 cm −1 .…”

The pentazolate anion, as a polynitrogen species, holds great promise as a high-energy density material for explosive or propulsion applications. Designing pentazole complexes that contain minimal non-energetic components is desirable in order to increase the material’s energy density. Here, we report a solvent-free pentazolate complex, AgN5, and a 3D energetic-framework, [Ag(NH3)2]+[Ag3(N5)4]ˉ, constructed from silver and cyclo-N5ˉ. The complexes are stable up to 90 °C and only Ag and N2 are observed as the final decomposition products. Efforts to isolate pure AgN5 were unsuccessful due to partial photolytical and/or thermal-decomposition to AgN3. Convincing evidence for the formation of AgN5 as the original reaction product is presented. The isolation of a cyclo-N5ˉ complex, devoid of stabilizing molecules and ions, such as H2O, H3O+, and NH4+, constitutes a major advance in pentazole chemistry.

“…Significant difference in materials systems in the reactive silver inks and the conventional metal nanoparticle inks introduces the reactive silver ink's advanced processability in the inkjet system. The dimension of molecules in reactive silver inks is less than 10 Å, which is much smaller than conventional metal nanoparticles (>5 nm) . This enables fluids not to get clogged in the finite dimension of nozzles (≤100 µm) .…”

In this work, a novel technique of inkjet printing e-textiles with particle free reactive silver inks on knit structures is developed. The inkjet-printed e-textiles are highly conductive, with a sheet resistance of 0.09 Ω sq -1 , by means of controlling the number of print passes, annealing process, and textile structures. It is notable that the inkjet process allows textiles to maintain its inherent properties, including stretchability, flexibility, breathability, and fabric hand after printing process. This is achieved by formation of ultrathin silver layers surrounding individual fibers. The silver layers coated on fibers range from 250 nm to 2.5 µm, maintaining the size of interstices and flexibility of fibers. The annealing process, structure of fibers, and printed layers significantly influence the electrical conductivity of the patterned structures on textiles. Outstanding electrical conductivity and durability are demonstrated by optimizing print passes, controlling textile structures, and incorporating an in situ annealing process. The electrical resistance dependence on the strain rate of the textiles is examined, showing the ability to maintain electrical conductivity to retain light-emitting diode use, stable more than 500 consecutive strain cycles. Most importantly, inkjet-printed e-textiles maintain their characteristic washability, breathability, and fabric hands for applications in wearable technology.

“…In all cases known to date, with half a dozen of different anions X À , the cations are aggregated to form chains by argentophilic contacts with Ag-Ag distances in the narrow range of 2.9-3.1 and linearity for the Ag-Ag-Ag assembly, including cases where polymorphism occurs (4). [46][47][48][49][50] The N-Ag-N axes of neighboring cations are generally close to orthogonal (staggered with regard to the Ag-Ag axis), but with an exchange of the anions the dihedral angles N-Ag-Ag-N nevertheless may deviate from the 908 standard very considerably. In all comparable cases (with the same anions, investigated at about the same temperature), the distances are only slightly larger (by ca.…”

Argentophilic Interactions

The decade 1990-2000 saw a growing interest in aurophilic interactions in gold chemistry. These interactions were found to influence significantly a variety of structural and other physical characteristics of gold(I) compounds. The attention paid to this unusual and counterintuitive type of intra- and intermolecular bonding between seemingly closed-shell metal centers has rapidly been extended to also include silver chemistry. Hundreds of experimental and computational studies have since been dedicated to the argentophilicity phenomenon. The results of this development are reviewed herein focusing on molecular systems where two or more silver(I) centers are in close contact leading to specific structural characteristics and a variety of novel physical properties. These include strongly modified ligand-to-metal charge-transfer processes observed in absorption and emission spectroscopy, but also colossal positive and negative thermal expansion on the one hand and unprecedented negative linear compressibility of crystal parameters on the other.
