Self-assembly of Ag(I)-based complexes and layered coordination polymers bridged by (2-thiazolyl)sulfides

Dinuclear complex, [Ag-2(2-Mt)(2)(MeCN)(2)(NO3)(2)] (1) as well as layered (2D) coordination polymers (CPs), [Ag-2(2-Mt)(2)(NO3)(2)](n) (2) and [Ag-4(2-Mt)(4)(NO3)(4)center dot 2H(2)O](n) (3), are self-assembled from 2-(methylthio)thiazole (2-Mt) and AgNO3 under different conditions. These compounds contain a [Ag-2(2-Mt)(2)] unit consisting of two metal atoms bridged by 2-Mt ligands (mu(2)-N,S) in head-to-tail (for 1 and 2) and head-to-head (for 3) manner. 2-(Methylthio)benzothiazole (2-Mbt) reacts with AgNO3 to assemble complex [Ag-2(2-Mbt)(2)(MeCN)(2)(NO3)(2)] (4), showing interesting dual emission behavior associated with the presence of fluorescence and phosphorescence, contributions of which depends on the excitation wavelength.
