Summary
Bu çalışmada yeni sentezlenmiş 12 disiyanidogümüş içeren bileşiklerin ([Ni(hydeten)2Ag(CN)2][Ag(CN)2].H2O (K1), [Cd2(hydeten)2Ag4(CN)8].H2O (K2), [Ni(bishydeten)2Ag(CN)2][Ag(CN)2].H2O (K3), [Cu(bishydeten)2Ag2(CN)4] (K4), [Cd(bishydeten)0.5]2[Ag(CN)2]4.3H2O (K5), [Ni(N-bishydeten)Ag3(CN)5] (K6), [Cu(N-bishydeten)Ag3(CN)5] (K7), [Zn(N-bishydeten)Ag3(CN)5] (K8), [Cd(N-bishydeten)]4[Ag(CN)2]8[Ag(CN)]2 (K9), [Cu(edbea)Ag2(CN)4].H2O (K11), [Cd(edbea) 2][Ag(CN)2]2.H2O (K12), ve [Cd(edbea)Ag3(CN)5] (K13) farklı dozlarının (5, 10, 15, 20, 30 and 40 µg/ml) Pseudomonas syringae pv. tomato (Pst), Clavibacter michiganensis subsp. michiganensis (Cmm) ve Xanthomonas axonopodis pv. vesicatoria (Xav) üzerindeki antibakteriyel etkileri belirlenmiştir. Test yöntemi olarak agar kuyucuk difüzyon yöntemi kullanılmıştır. En iyi sonuç K9 maddesinden elde edilmiş olup, bakterilerin koloni gelişimini %90 ve üzerinde engellemiştir. 12 maddeden 8 tanesinin Cmm’in gelişimini %90 ve üzerinde engelledikleri belirlenmiştir. K11 ve K12 maddeleri testlenen bakterileri %72 ile %100 arasında değişen oranlarda engellemişlerdir. Pst üzerinde K9 ve K3 maddeleri sırasıyla %93,83 ve %85,71 oranlarında etkili olurken, en düşük etki 40 µg/ml dozu ile K4 (%33) maddesinde belirlenmiştir. Diğer taraftan Xav üzerinde en yüksek etki %99 oran ile 40 µg/ml dozlu K13 maddesinde görülmüştür. Bu maddelerin çoğunluğunda antibakteriyel etkilerine yönelik ümit var sonuçlar elde edilmiştir. Ancak bu maddelerin tarla koşullarında etkinliklerini belirlemeye yönelik çalışmaların yapılması gerekmektedir.

Abstract
In current study, different concentrations (5, 10, 15, 20, 30 and 40 µg/ml) of twelve the newly synthesized bimetallic cyanido complexes ([Ni(hydeten)2Ag(CN)2] [Ag(CN)2].H2O (K1), [Cd2(hydeten)2Ag4(CN)8].H2O (K2), [Ni(bishydeten)2Ag(CN)2] [Ag(CN)2].H2O (K3), [Cu(bishydeten)2Ag2(CN)4] (K4), [Cd(bishydeten)0.5]2[Ag(CN)2]4.3H2O (K5), [Ni(N-bishydeten)Ag3(CN)5] (K6), [Cu(Nbishydeten)Ag3(CN)5] (K7), [Zn(N-bishydeten)Ag3(CN)5] (K8), [Cd(N-bishydeten)]4[Ag(CN)2]8[Ag(CN)]2 (K9), [Cu(edbea)Ag2(CN)4].H2O (K11), [Cd(edbea)2][Ag(CN)2]2.H2O (K12) and [Cd(edbea) Ag3(CN)5] (K13) were evaluated for their antibacterial activity against Pseudomonas syringae pv. tomato (Pst), Clavibacter michiganensis subsp. michiganensis (Cmm) and Xanthomonas axonopodis pv. vesicatoria (Xav). Antibacterial activity was determined using the agar well diffusion assay method. The best results were demonstrated by compound K9, it possessed over 90% inhibition on the bacterial growth. Eight out of 12 compounts exhibited over 90% inhibition on Cmm. Inhibitory effects of K11 and K12 on test bacteria were varied between 72% and 100%. It was observed that K9 and K3 showed highly significant antibacterial activity with 93.83% and 85.71% inhibitions against Pst respectively, whereas the lowest activity was observed in K4 (33%) at 40 µg/ml against the bacterial pathogens tested. On the other hand compound K13 exhibited the highest antibacterial activity against Xav with 99% growth inhibition at 40 µg/ml. Most of these compounds showed promising activities against the tested bacteria. Further studies should be conducted to test the efficacy of these compounds under field conditions.
