Synthesis and structure of [Na(15-crown-5)][Ph ₂ P(S)OB(C ₆ F ₅ ) ₃ ] and [Na(15-crown-5) ₂ ][Ph ₂ P(S)O···HO(S)PPh ₂ ]

Abstract

Abstract The reaction of Ph 2 P(S)ONa with B(C 6 F 5 ) 3 in the presence of the crown ether 15-crown-5 provided the borate complex [Na(15-crown-5)][Ph 2 P(S)OB(C 6 F 5 ) 3 ] ( 1 ). In one occasion a few crystals of the hydrogen-bonded complex [Na(15-crown-5) 2 ][Ph 2 P(S)O···HO(S)PPh 2 ] ( 2 ) were obtained, which formed upon the accidental hydrolysis of 1 . More rationally, 2 was prepared by the reaction of Ph 2 P(S)OH, Ph 2 P(S)ONa and 15-crown-5. The molecular structures of 1 and 2 were investigated by X-ray crystallography.
