| Summary: | In the title compound, [(Ph3P)2N]+·[Cl-H-Cl]− or C36H30NP2+·Cl2H−, the H atom of the [Cl—H—Cl]− anion and the N atom of the [(Ph3P)2N]+ cation are located on a twofold axis, yielding overall symmetry 2 for both the cation and the anion. The central P—N—P angle [144.12 (13)°] of the cation is in the expected range and indicates only weak cation–anion interactions. The almost linear [Cl—H—Cl]− anion is a rare example of a symmetric hydrogen bridge in a hydrogen dichloride anion. The Cl...Cl distance and two equal Cl—H bonds are typical of such a symmetric hydrogen dichloride anion. |
