Preparation and Reactivity of a Triphosphenium Bromide Salt: A Convenient and Stable Source of Phosphorus(I)
Published on: November 22, 2016
Bis[4-(4-chloro-phen-yl)-4-hydroxy-piperidinium] dipicrate dimethyl sulfoxide solvate
Abstract:
The asymmetric unit of the title salt solvate, 2C(11)H(15)ClNO(+)·2C(6)H(2)N(3)O(7) (-)·C(2)H(6)OS, contains two crystallographically independent 4-(4-chloro-phen-yl)-4-hydroxy-piperidinium cations, two picrate anions and a dimethyl sulfoxide solvent mol-ecule. In each cation, the piperidinium ring adopts a chair conformation. In the crystal structure, the cations, anions and solvent mol-ecules are connected by inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.

Solubility
A solution is a homogeneous mixture composed of a solvent, the major component, and a solute, the minor component. The physical state of a solution—solid, liquid, or gas—is typically the same as that of the solvent. Solute concentrations are often described with qualitative terms such as dilute (of relatively low concentration) and concentrated (of relatively high concentration).
In a solution, the solute particles (molecules, atoms, and/or ions)...
