For compounds of the type [(MeO-BIPHEP)PdX2](where MeO-BIPHEP is (6,6'-dimethoxybiphenyl-2,2'-diyl)bis(diphenylphosphine) and X is an anionwith low coordination ability)one or both anions X, depending on their nature, are displaced in anouter coordinationsphere due to water coordination. The compounds are easily reducedin methanolic solution.With the diaquo complex[{(S)-MeO-BIPHEP}Pd(H2O)2](OTf)2as starting material, theformation of the dimeric palladium(I) complex[{(S)-MeO-BIPHEP}Pd]2(OTf)2is observed.In contrast, under CO pressure, the 
-hydrido -carbonylbinuclear palladium(I) complex[{(S)-MeO-BIPHEP}Pd(-H)(-CO)Pd{(S)-MeO-BIPHEP}]OTfis formed. The molecularstructures of[{(S)-MeO-BIPHEP}Pd(H2O)(THF)](OTf)2and[{(S)-MeO-BIPHEP}Pd(OTfa)2]were determined by X-ray diffraction.
