“…7 The increased antimicrobial activity of silver nitrile complexes resulting from the facile release of Ag + ions from labile complexes was suggested by Han et al 16 So far, we have obtained and described the molecular structures of several molecular compounds and coordination polymers linked by cyanopyridine and dicyanobenzene ligands, and initially investigated their luminescent properties. 17 Within the present study, we are expanding the library of the nitrile complexes of silver with new molecular and polymeric species. Moreover, we study the antimicrobial activity of the large group of silver nitrile complexes and juxtapose the results with the antimicrobial activity of simple silver salts and organic nitriles.…”

In the present study, the structure, thermal stability, conductive properties, and antimicrobial activity of silver(I) complexes with nitrile ligands were investigated. For the construction of the materials, 2‐cyanopyridine (2‐cpy), 4‐cyanopyridine (4‐cpy), 1,2‐dicyanobenzene (1,2‐dcb), and 1,3‐dicyanobenzene (1,3‐dcb) were used in addition to the silver nitrite and nitrate. Four new compounds were isolated and structurally characterized: one molecular complex [Ag4(1,2‐dcb)4(NO3)4], two 1‐D coordination polymers [Ag(2‐cpy)2(NO2)]∞, [Ag2(1,3‐dcb)2(NO3)2]∞, and one 3‐D coordination polymer [Ag(4‐cpy)(NO2)]∞. The results indicate that the nitrile complexes display good antimicrobial properties against the tested bacterial and fungal strains. The presence of weakly coordinating CN groups increases the release of silver ions into the bacterial and yeast cell environments. Moreover, these materials exhibit unusual electrical properties in thin‐layer devices. On the other hand, the nitrite and nitrate counterions give rise to the low thermal stability of the complexes.
