1-Chloromethyl-1,4-diazoniabicyclo[2.2.2]octane bis(hexafluorophosphate)

Abstract

In the crystal structure of the title compound, C7H15ClN2 2+·2PF6 −, the cations and anions are linked by inter­molecular N—H⋯F hydrogen bonds.

Synthesis, characterization and disorder–order phase transition of inorganic–organic hybrid materials (H2dabco-CH2-Cl)[MIICl4] (M = Co, Zn)

“…1-(Chloromethyl)-1,4-diazabicycloij2.2.2]octan-1-ium chloride, (Hdabco-CH 2 -Cl)Cl, was synthesized according to a method reported previously. 30 Elemental analyses were carried out on an Elementar vario EL cube analyzer. Thermogravimetric (TG) measurements were performed using a Netzsch STA 449F3 instrument under flowing air atmosphere with a heating rate of 10 K min −1 .…”

Temperature-induced reversible structural phase transition of 1-(chloromethyl)-1,4-diazoniabicyclo[2.2.2]octane bis(perchlorate)

“…1-(Chloromethyl)-1,4-diazabicyclo[2.2.2]octan-1-ium chloride was synthesized according to the method reported previously. 10 Infrared spectra were recorded on a SHIMADZU IR prestige-21 FTIR-8400S spectrometer in the range of 4000-600 cm −1 with samples in the form of potassium bromide pellets. The IR spectrum of 1 shows a strong vibration peak between 1150 and 1080 cm −1 , indicating the existence of a perchlorate anion (Fig.…”
