Abstract
Two new carboxylate silver(I) complexes, namely [Ag 2 (C 4 H 6 O 4 N)]NO 3 · H 2 O or [Ag 2 (HIDA)]NO 3 · H 2 O with IDA = iminodiacetate (1) and Ag 6 (C 6 H 6 O 6 N) 2 or Ag 6 (NTA) 2 with NTA = nitrilotriacetate (2) are synthesized and characterized by X‐ray powder diffraction, thermal analysis and infrared spectroscopy. Rietveld refinement reveals [Ag 2 (HIDA)]NO 3 · H 2 O to form a 2D coordination polymer while Ag 6 (NTA) 2 forms a 3D network, both featuring short Ag(d 10 )–Ag(d 10 ) contacts. The resulting complexes are suitable precursors for the printing of silver structures at low temperature, in particular for micro and submicrometer patterns obtained via nanoimprint lithography. The patterns reveal low specific resistivity ( ρ ≈ 10 –7 Ω m) and good transmittance (> 50 %) in the visible range enabling applications in optoelectronic devices.
