Synthesis,Crystal Structure and Luminescence of [Ag(PPh3)2(H2TMT)]

The silver complex Ag(PPh₃)₂(H₂TMT) ( 1 )(H₃TMT = 2,4,6‐trimercapto‐1,3,5‐triazine) has been synthesized and characterized. The ligand trimercaptotriazine exhibits a novel coordination mode and the complex shows a special hydrogen bonding linkage in the crystal packing. The colorless crystals of 1 exhibit broad emission in the visible region at room temperature. TDDFT calculation indicated that the π–π attraction is crucial for fluorescence of the title complex.
