Lewis‐Base Stabilized N‐Silver(I) Succinimide Complexes: Synthesis, Crystal Structures and Their Use as CVD‐Precursors

Abstract

AbstractFour Lewis‐base stabilized N‐silver(I) succinimide complexes of type [Ln·Rm·AgNC4H4O2] (L = N,N,N′,N′‐tetramethylethylenediamine (TMEDA), n = 1, m = 0, 2a; L = P(OEt)3, n = 2, m = 0, 2b; L = PPh3, m = 0, n = 2, 2c; L = P(OMe)3, R = TMEDA, n = 1, m = 1, 2d) were prepared by a “one‐pot” synthesis methodology and characterized. The molecular structures of 2a and 2c have been determined by using X‐ray single crystal analysis. Complex 2a exists as ion pair {[Ag(TMEDA)2]+[Ag(NC4H4O2)2]–} in the solid state and complex 2c is a monomer with the three‐coordinate silver atom. Complex 2b was used as precursor in the deposition of silver for the first time by using MOCVD technique. The silver films obtained were characterized using scanning electron microscopy (SEM) and energy‐dispersion X‐ray analysis (EDX). SEM and EDX studies show that the dense and homogeneous silver films could be obtained.
