Six organophosphine/phosphite‐stabilized silver(I) N ‐hydroxysuccinimide complexes of type [C 4 H 4 NO 3 Ag⋅L n ] (L = PPh 3 ; n = 1, 2a; n = 2, 2b; L = P(OEt) 3 ; n = 1, 2c; n = 2, 2 d; L = P(OMe) 3 ; n = 1, 2e; n = 2, 2f) were prepared. These complexes were obtained in high yields and characterized by elemental analysis, 1 H NMR, 13 C{ 1 H} NMR and IR spectroscopy, respectively. The molecular structure of 2b has been determined by X‐ray single‐crystal analysis in which the silver atom is in a distorted tetrahedral geometry. An interstitial methanol solvent molecule is hydrogen bonded to the oxygen atom of N ‐hydroxysuccinimide molecule. Complex 2f was used to deposit silver films by metal‐organic chemical vapor deposition (MOCVD) for the first time. The silver film obtained at 480 °C is dense and homogeneous, which is composed of many well‐isolated, granular particulates spreading all over the substrate surface.
