Phosphonium Hydrogendichlorides, II: Three Crystal Structures in ComparisonBy means of crystal structure analysis the compounds [(4-CH3OC6H4)(CH3)PCl2][ClHCl] (1), [(4-CH3OC6H4)PCl3][ClHCl] (2), and [(4-C2H5OC6H4)PCl3][ClHCl] (3) are confirmed as phosphonium hydrogendichlorides and the number of existing geometric parameters of hydrogen bonding between Cl atoms in crystals is substantially increased. The symmetric hydrogendichloride anions who the shortest distances Cl…Cl (312.1 pm in 2) and the largest distance of this kind (328.8 pm also in 2) is observed in the anion with the shortest Cl-H bond.
Notes:
Durch Kristallstrukturanalyse werden die Verbindungen [(4-CH3OC6H4)(CH3)PCl2][ClHCl] (1), [(4-CH3OC6H4)PCl3][ClHCl] (2) und [(4-C2H5OC6H4)PCl3][ClHCl] (3) als Phosphonium-hydrogendichloride bestätigt und die vorhandenen geometrischen Daten zur Wasserstoffbrückenbindung zwischen Cl-Atomen in Kristallen deutlich vermehrt. Die symmetrischen Hydrogendichlorid-Anionen zeigen die kürzesten Abstände Cl…Cl (312.1 pm in 2), und der längste Abstand dieser Art (328.8 pm ebenfalls in 2) wird beim Anion mit der kürzesten Bindung Cl—H beobachtet.
