Abstract

The central AgI atom of the title salt, [Ag(INAM)2](CF3SO3)·2CH3CN, where INAM is isonicotinamide (C6H6N2O), is twofold coordinated by the pyridine N atoms of two isonicotinamide ligands creating a slightly distorted linear mol-ecular geometry. The formation of polymeric chains {[Ag(INAM)2]+} n , held together by discrete hydrogen bonds through the amide group of the INAM ligand leaves voids for non-coordinating aceto-nitrile mol-ecules that inter-act the silver metal center via regium bonds.

Highlights

The central AgI atom of the title salt, [Ag(INAM)2](CF3SO3)Á2CH3CN, where INAM is isonicotinamide (C6H6N2O), is twofold coordinated by the pyridine N atoms of two isonicotinamide ligands creating a slightly distorted linear molecular geometry
Silver(I) isonicotinamide complexes have been investigated for the ability to form coordination complexes with a variety of molecular geometries due to amide hydrogenbond synthons in their structure (Aakeroy & Beatty, 1998; Aakeroy et al, 1998; Lian et al 2007), luminescent properties (Yesilel et al, 2012), and antibacterial activity (AbuYoussef et al, 2007; Yu et al, 2020)
Our research group interest currently lies in the synthesis of novel metal complexes with biological activity; as part of our research in this area, we describe the synthesis and structure of the title silver(I) complex

Summary

Structure description

Silver(I) isonicotinamide complexes have been investigated for the ability to form coordination complexes with a variety of molecular geometries due to amide hydrogenbond synthons in their structure (Aakeroy & Beatty, 1998; Aakeroy et al, 1998; Lian et al 2007), luminescent properties (Yesilel et al, 2012), and antibacterial activity (AbuYoussef et al, 2007; Yu et al, 2020). Our research group interest currently lies in the synthesis of novel metal complexes with biological activity; as part of our research in this area, we describe the synthesis and structure of the title silver(I) complex. The asymmetric unit of the title compound shows the AgI ion in a distorted linear coordination environment defined by two N-bonded isonicotamide ligands. Two acetonitrile molecules and a trifluoromethanesulfonate ion complete the asymmetric unit; the acetonitrile molecules sit at opposite sides of the plane defined by N1—Ag1—N3 with the nitrile group facing the silver(I) metal center. The angle N1—Ag1— N3 of 172.78 (7) is within the reported values (174.9, 180, and 171.1) in the comparable silver(I) isonicotinamide structures currently available in the CSD
