Abstract

Two new silver(I) compounds, [Ag(4-dmapy)2(p-bromophenylacetate)] · H2O (1) and [Ag(4-dmapy)2(p-hydroxyphenylacetate)]·2H2O (2) (4-dmapy = 4-dimethylaminopyridine), have been synthesized and characterized. X-ray crystallographic analysis reveals that 1 and 2 contain a linear Ag(4-dmapy)2 chromophore, which further forms dimeric silver(I) units via weak silver–silver interaction. The short Ag ··· Ag separations in 1 and 2 are 3.0395(12) and 3.2697(10) Å, respectively. Compounds 1 and 2 have good anti-Bacillus subtilis activity in vitro (minimum inhibitory concentration, MIC = 12.5 µg mL−1) but were inactive against Staphylococcus aureus and Escherichia coli (MIC > 50 µg mL−1).
