Abstract
PPh3Me[HSO4] was prepared by the reaction of (PPh3Me)I with silver sulfate in aqueous solution. OPPh2Me and benzene being the by-products. The title compound was characterized by its IR spectrum as well as by an X-ray structure determination (1730 observed independent reflexions, R = 0.043). Crystal data: a = 910.4(3). b = 1587.8(4), c = 1294.2(6) pm, β = 105.52(3)°. space group P21/c, Z = 4. The structure consists of PPh3Me⊕ cations and of HOSO3⊖ ions that are associated via strong hydrogen bonds to dimeric centrosymmetric units.
