] (

), have been synthesized and structurally characterized by X-ray crystallography. These compounds exhibit a coordinated silver column structure with OTf
−
/POM anions serving as counter-anions (
1
,
6
), an infinite chain structure based on the coordinated Ag
4
aggregates and POM anions (
2
,
3
) and a discrete molecular structure containing coordinated silver aggregates and POM anions (
4
,
5
), respectively. The pure phases of
1-5
are obtained and identified. The antibacterial/antifungal activities of
1-5
are screened by the disk diffusion method against the bacteria strains
Bacillus pumilus
,
Bacillus subtilis
,
Staphylococcus aureus
and
Escherichia coli
and the fungi strains
Aspergillus niger
and
Canidia albicans
, and the MIC/MBC values are also measured. The cytotoxicity and biological toxicity test results showed that these compounds have low toxicity in both cells and animals.
Six new silver-phenylethynide double salts with the crystal structures of a coordinated silver column (
1
,
6
), an infinite silver chain (
2
,
3
) and a discrete molecule (
4
,
5
) have been synthesized and structurally characterized. The pure phases of
1-5
are obtained and found to have antibacterial and antifungal properties. |
