Synthesis and structural characterization of mixed-ligand silver(I) complexes containing diphosphazanes and bidentate N-donor ligands

摘要: The reactions of a self-assembled silver(I) coordination polymer, [Ag2{μ-PriN(PPh2)2}(μ-NO3)2]n (1) with various bidentate N-donor ligands such as DABCO, 2,2′-bipyridyl and 1,10-phenanthroline yield 1-D helices or π–π stacked polymers, depending on the chelate vector ligand. molecular structures resultant complexes, [Ag2{μ-PriN(PPh2)2}(DABCO)(NO3)2]n (2), [Ag2{μ-PriN(PPh2)2}(2,2′-bipy)2(NO3)2] (3) [Ag2{μ-PriN(PPh2)2}(1,10-phen)2](NO3)2 (4) have been confirmed by single-crystal X-ray diffraction. Complex 2 exists an infinite helical polymer because exo-bidentate nature DABCO. 3 assumes 2D grid motif result intermolecular stacking among adjacent bipyridine moieties. phenanthroline complex 4 exhibits strong inter- intramolecular interactions.
