3‐[(Diphenylphosphinothioyl)oxy]‐N‐methylpropan‐1‐aminium diphenylphosphanylthioate. Issue 3 (22nd February 2014) - Karaman, Merve
Abstract The title salt, C16H21NOPS+·C12H10OPS, was synthesized from the reaction between 3‐(methylamino)propan‐1‐ol and PPh2(S)Cl in the presence of Et3N. Its structure has been identified using spectroscopic methods and X‐ray analysis. Single crystals were obtained from ethanol by slow evaporation. In the asymmetric unit, a cation–anion pair is formed through an intermolecular N—H...O [N...O = 2.6974 (18) Å] hydrogen bond. The molecules are packed through N—H...O and N—H...S hydrogen bonds in the crystal and these hydrogen bonds are responsible for the high melting point. The P atoms of the anion and cation both have distorted tetrahedral environments.
