A polymorph of tetraethylammonium chloride
The structure of the title compound, C(8)H(20)N(+)·Cl(-), is compared with a polymorph that was described earlier in the same space group. Differences in the conformations of the ethyl groups of the cation exist between the polymorphs. This study is given here in order to provide additional unit-cell data for use in qualitative identification of crystalline samples obtained in syntheses in whic...
متن کاملA triclinic polymorph of 3-nitroanilinium chloride
The asymmetric unit of the title compound, C(6)H(7)N(2)O(2) (+)·Cl(-), contains two independent ion pairs. A monoclinic form of the title compound with only one ion pair in the asymmetric unit has been reported previously [Ploug-Sørensen & Andersen (1986). Acta Cryst. C42, 1813-1815]. In the crystal of the title compound, the components are linked into layers parallel to (001) by inter-molecula...
متن کاملThe use of tetraethylammonium chloride in treatment of phantom limb.
M UCH has been written in regard to the treatment of phantom leg symptoms. It is readily conceded that there is no comprehensible explanation for the phantom illusion, yet this does not exclude the fact that there is such a symptom complex. After amputation of an extremity it is usual for the patient to have sensations which seem to orignate in the absent limb. In the majority of cases these se...
متن کاملA second monoclinic polymorph of 2,4-dimethylanilinium chloride
A second monoclinic polymorph of 2,4-dimethyl-anilinium chloride, C(8)H(12)N(+)·Cl(-), (I), is reported. The unit-cell dimensions differ from those of the first reported monoclinic form, (II) [Yao (2010 ▶). Acta Cryst. E66, o1563]. Nevertheless, both compounds crystallize in the monoclinic space group P2(1)/n. As in (II), the protonated amine group in (I) acts as a hydrogen-bond donor to the ch...
متن کاملBlock of neuronal chloride channels by tetraethylammonium ion derivatives
The block by the symmetric tetraethylammonium (TEA) ion derivatives tetrapropylammonium (TPrA), tetrabutylammonium (TBA), and tetrapentylammonium (TPeA) ions of fast chloride channels in acutely dissociated rat cortical neurons was studied with the excised inside-out configuration of the patch-clamp technique. When applied to the intracellular membrane surface, all three of the quaternary ammon...
