摘要: Abstract Oxybis(triphenylbismuth) derivatives (Ph3BiOBiPh3)X2 where X=CIO4, NO3, Cl, Br, NCO and CF3COO have been prepared their structural characteristics determined by infrared spectroscopy conductance measurements. In the solid state a non-ionic structure in which X groups act as monodentate ligands, is indicated for these compounds. Conductance studies show that maintained acetonitrile except = ClO4. The diperchlorate forms dihydrate also appears to an ionic well acetonitrile. spectroscopic data anhydrous hydrated dichloromethane suggest presence of ion-pairs or species. Triphenylbismuth oxide has isolated its spectrum indicates it polymeric containing-BiOBi- units. BiOBi stretching frequencies compounds assigned.
