Bis(triphenyl-λ⁵-phosphanylidene)ammonium hydrogen dichloride

Abstract

Bis(triphenyl-λ 5-phosphanylidene)ammonium hydrogen dichloride Jorit Gellhaar and Carsten Knapp S1. Comment The Cambridge Structural Database (Allen, 2002) currently contains more than 1200 structures containing the [(Ph 3 P) 2 N] + cation ([(Ph 3 P) 2 N] + = [PNP] +). Usually this cation is partnered by a bulky anion, while crystal structures

Reactivity of Ruthenium Phosphido Species Generated through the Deprotonation of a Tripodal Phosphine Ligand and Implications for Hydrophosphination

“…Another feature of note is the presence of the hydrogen dichloride anion, where the additional equivalent of HCl is not removed when the crystals are exposed to reduced pressure. The proton sits between the two chlorine atoms with Cl(1)–HCl(2) and Cl(2)–HCl(1) bond lengths of 1.55(9) and 1.58(9) Å, respectively, which are comparable to the distances for other hydrogen dichloride anions reported in the literature. − …”

Supramolecular fluoride and chloride anions

“…À ions exist in nineteen different crystal lattices, but the d values provide no definitive boundary between the two forms (ClHCl) À and (Cl)(HCl) À . At the extremes are the bichloride ion in AZOLUX ( [18], Fig. 7) and its hydrogen-bonded counterpart in TARFEX ( [34], Fig.…”
