Two new carboxylate silver(I) complexes, namely [Ag2(C4H6O4N)]NO3·H2O or [Ag2(HIDA)]NO3·H2O with IDA = iminodiacetate (1) and Ag6(C6H6O6N)2 or Ag6(NTA)2 with NTA = nitrilotriacetate (2) are synthesized and characterized by X‐ray powder diffraction, thermal analysis and infrared spectroscopy. Rietveld refinement reveals [Ag2(HIDA)]NO3·H2O to form a 2D coordination polymer while Ag6(NTA)2 forms a 3D network, both featuring short Ag(d10)–Ag(d10) 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.
