Tetramethylammonium hydroxide poisoning

Clinical Toxicology, 2010
Tetramethylammonium hydroxide (TMAH) is widely used as a developer or etchant in semiconductor and photoelectric industries. In addition to alkalinity-related chemical burn, dermal exposure to TMAH may also result in respiratory failure and/or sudden death.

Static Compression of Tetramethylammonium Borohydride

The Journal of Physical Chemistry A, 2011
Raman spectroscopy and synchrotron X-ray diffraction are used to examine the high-pressure behavior of tetramethylammonium borohydride (TMAB) to 40 GPa at room temperature. The measurements reveal weak pressure-induced structural transitions around 5 and 20 GPa. Rietveld analysis and Le Bail fits of the powder diffraction data based on known structures

Phase transitions in tetramethylammonium manganese chloride and tetramethylammonium cadmium chloride

Physics Letters A, 1971
Abstract The order-disorder type phase transitions in (CH 3 ) 4 NMCl 3 (at 128°K) and (CH 3 ) 4 NCdCl 3 (at 154°K) have been studied by single crystal X-ray and Raman scattering techniques.

Synthesis and Characterization of Tetramethylammonium Trifluorosulfate

Chemistry – A European Journal, 2010
Abstract[Me4N]+[SO2F3]−, the first example of a [SO2F3]− salt, has been prepared from Me4NF and SO2F2. The colorless, microcrystalline solid was characterized by its infrared and Raman spectra. The trigonal bipyramidal structure of C2v symmetry of the [SO2F3]− anion is predicted by ab initio calculations.

Tetramethylammonium 2,5-dinitrophenolate monohydrate

Acta Crystallographica Section C Crystal Structure Communications, 2005
The crystal structure of the title compound, C4H12N+.C6H3N2O5-.H2O, is built up from tetramethylammonium cations, 2,5-dinitrophenolate anions and water molecules. The nitro groups are almost coplanar with the aryl ring, which exhibits significant distortion from an ideal hexagonal form.

Tetrakis(tetramethylammonium) tricarbonatodioxidouranate octahydrate

Acta Crystallographica Section C Crystal Structure Communications, 2011
The environment of the U atom in the title compound, (C(4)H(12)N)(4)[UO(2)(CO(3))(3)]·8H(2)O, presents a typical hexagonal bipyramidal geometry found in many actinide complexes. It is a model for actinide species and consists of common environmental moieties (carbonate, water and ammonia species).
