Two dinuclear and centrosymmetric silver-containing complexes, namely [Ag₂(3,5-dmpz)₂(3,5-dmpz methanol)₂(tbtc)] (1) and [Ag₂(3,5-dmpz)₂(3,5-dmpz methanol)₂(dbtc)] (2) (3,5-dmpz: dimethylpyrazole; 3,5-dmpz methanol: 3,5-dimethylpyrazole methanol; H₂tbtc: tetrabromoterephthalic acid; H₂dbtc: 2,5-dibromoterephthalic acid), were prepared and characterized. X-ray crystallographic data of 1 and 2 revealed that trigonal environment of the Ag ions has a “compressed Y’s” geometry. The antimicrobial activity of 1 and 2 was tested against the Gram-positive, Gram-negative bacteria and fungus, displaying the better inhibiting activity than the individual AgNO₃ and 3,5-dimethylpyrazole, especially for Candida albicans (IC₅₀ 2.5 ± 0.1 mg mL ⁻¹ and 2.8 ± 0.2 mg mL⁻¹). The quantified IC₅₀ values displayed that complexes 1 and 2 were more effective against fungus than the Gram-negative bacteria and Gram-positive bacteria.

两种双核中心对称含银配合物，即[Ag ₂ (3,5-dmpz) ₂ (3,5-dmpz 甲醇) ₂ (tbtc)] ( 1 ) 和 [Ag ₂ (3,5-dmpz) ₂ ( 3,5-dmpz 甲醇) ₂ (dbtc)] ( 2 ) (3,5-dmpz：二甲基吡唑；3,5-dmpz 甲醇：3,5-二甲基吡唑甲醇；H ₂ tbtc：四溴对苯二甲酸；H ₂ dbtc：2 ,5-二溴对苯二甲酸），进行了制备和表征。1和2的X射线晶体学数据表明Ag离子的三角环境具有“压缩Y”几何形状。测试了1和2对革兰氏阳性、革兰氏阴性细菌和真菌的抗菌活性，显示出比单独的AgNO ₃和3,5-二甲基吡唑更好的抑制活性，特别是对白色念珠菌（IC ₅₀ 2.5 ± 0.1 mg） mL  ^-1和 2.8 ± 0.2 mg mL ^-1 )。定量的IC ₅₀值显示复合物1和2比革兰氏阴性菌和革兰氏阳性菌更有效地对抗真菌。
