This work describes the synthesis of novel complexes of silver(I) and triphenylphosphine using thiocyanate ligands, 2-mercaptoethanol and 2-amino-2-methylpropanol, from a mild method, efficiently and with good yields. We tested the reactivity of Ag(I) compared to bidentate ligands, we observed that the reaction was effective for sulfur and nitrogen atoms, binders containing oxygen was not possible to complex with Ag (I), using our methodology. Studies have shown that molecules containing silver (I) and spacer linkers can be used as molecules with potential biological activities. The synthesized compounds were characterized by techniques of IR spectroscopy, ultraviolet and x-ray fluorescence. The complexes have high fluorescence emission, mainly in the 380 nm range.
