Crystal structure of bis[tetrakis(triphenylphosphane-κP)silver(I)] (nitrilotriacetato-κ⁴N,O,O′,O′′)(triphenylphosphane-κP)argentate(I) with an unknown amount of methanol as solvate

Abstract

The structure of the title compound exhibits a trigonal (P-3) symmetry, with a C 3 axis through all three complex ions, resulting in an asymmetric unit that contains one third of the atoms present in the formula unit. Attempts to refine the solvent model were unsuccessful, indicating uninter­pretable disorder, which was handled using SQUEEZE.

Synthesis and Structure of the Silver(I) Complexes [Ag2(C4H6O4N)NO3]·H2O and Ag6(C6H6O6N)2 for the Formulation of Silver Inks in Nanoimprint Lithography

“…The tetradentate coordination by NTA results in a bonding of one nitrogen atom with one silver atom showing bond lengths of 2.44 Å (N11–Ag3) and 2.49 Å (N12–Ag6). The nitrogen‐bonded silver atoms Ag3 and Ag6 are additionally coordinated by 5 oxygen atoms in a AgO 5 coordination geometry (oblique pyramid) with distances from 2.28 Å to 2.75 Å (see Table ) in accordance with literature values (Figure a) , , . Silver atom Ag has an AgO 4 coordination geometry but with shorter Ag–O bond lengths (1.98 Å to 2.69 Å) than Ag3 and Ag6.…”

“…Structural analysis revealed the IDA complex to form a nitrate hydrate complex with Ag 2 O 2 units bonded over the nitrate and one IDA molecule resulting in a 2D supramolecular network. Based on former studies from Noll et al, we clarified the entire crystal structure of the NTA complex as a 3D network. Thermogravimetric studies allow for a better understanding of the thermal decomposition of the complexes which is important to evaluate the suitability of the complexes as silver inks for direct printing methods.…”

“…The synthesis of Ag 6 (NTA) 2 is modified from Noll et al Silver nitrate (1.02 g, 6 mmol) was dissolved in 10 mL of water. The ligand solution was prepared by dissolving nitrilotriacetic acid trisodium salt monohydrate (0.55 g, 2 mmol) in 10 mL of water.…”

“…Silver complexes have been widely investigated in recent years due to their capability of being processed easily in printing processes e.g. inkjet or gravure printing allowing for the preparation of transparent or semitransparent thin film electrodes . For the preparation of transparent conductive coatings various materials such as transparent conductive oxides (TCOs), carbon materials, conductive polymers and metals are used .…”
