| dc.abstract.en | Six new coordination polymers, namely, [Ag2L- (NO3)2]n (1), {[Ag6L4(CF3SO3)4][CF3SO3]2}n (2), {[Ag2L- (NO3)][ClO4]}n (3), {[Ag2L(NO3)][BF4]}n (4), {[Ag2L(NO3)]- [PF6]}n (5), and {[Ag2L(NO3)][SbF6]}n (6), have been successfully synthesized by the reaction of AgNO3 and selected coanions CF3SO3 −, ClO4 −, BF4 −, PF6 −, and SbF6 − with 1,3-bis(1- methylthioimidazolyl) propane under the same experimental conditions in order to illustrate coordination ability of nitrate ion relative to the other considered coanions. To evaluate this competition, compound 1 as a reference structure was synthesized in the absence of coanions. In its two-dimensional structure, the thione ligand appears in a hexadentate mode, and the nitrate as a coligand is coordinated in a bidentate fashion. In a competition between the silver nitrate and triflate, despite the coordination ability expected for both anions, these anions did not appeared together in the structure of compound. The moderately coordinating anion CF3SO3 − build up a cationic structure with only one kind of anion. In contrast to polymers 1 and 2, in the valuable networks 3−6, for the first time extraordinarily two kind of anions were involved in their structures. The difference between the coordination ability of the considered coanions is the most effective factor that impacts the coordination and linkage modes of the flexible ligand and nitrate anion and in turn directs the construction of coordination polymers. In general, X-ray diffraction analysis reveals that the most changes in the structure of compounds 3−6 relative to the structure of 1 were generated by the bulky, uncoordinated anions PF6 − and SbF6 −. The thermogravimetric analysis experimental data reveal that these compounds start to decompose in the temperature range of 140−328 °C. In their electronic spectra, a sharp band at 246 nm due to the π → π* transitions in the CS moiety of the ligand is slightly red-shifted upon coordination of the ligand to AgI ions via sulfur atoms. All of the synthesized compounds display strong blue emissions in the solid state. The title complexes possess antibacterial activity against the selected strain of Gram-negative (Escherichia coli, Pseudomonas aeruginosa) and Grampositive (Staphylococcus aureus, Bacillus subtilis) bacteria. |
