Abstract:
Two novel silver(I) complexes [Ag2Br2(DPEphos)(2)(dppe)](1) and [Ag(DPEphos)(dppe)]NO3(2) (DPEphos=his [2-(diphenylphosphino)phenyl]ether, dppe =bis (diphenylphosphino)ethane) have been synthesized and characterized by IR, single-crystal X-ray diffraction, H-1 NMR, P-3 NMR spectroscopy and fluorescence spectra. 1 is comprised of AgBr, DPEphos and dppe in 2:2:1 molar ratio generating a binuclear complex. The dppe ligand bridges two Ag atoms through two P atoms in 1. While, 2 is obtained by the reactions of AgNO3,DPEphos and dppe in 1:1:1 molar ratio generating a sample mono-nuclear complex. The Ag(I) atom is chelated by DPEphos and dppe ligand. In the P-31 NMR spectra of 2, there are four splitting signals (doublets or triplets). The luminescent spectra show that the origin of these emissions all involves emissive state derived from ligand centered pi-pi* transition. CCDC: 1043375, 1; 1043376, 2.
