The title compound, C(4)H(12)N(+)·C(8)H(11)NO(5)PS(-), was obtained from tetra-methyl-ammonium hydroxide and dimeth-yl(phenyl-sulfon-yl)amido-phosphate. The tetra-methyl-ammonium cation has a slightly distorted tetra-hedral configuration and the N-C bond lengths lie in the range 1.457 (3)-1.492 (3) Å. In the crystal, no classical hydrogen bonds are observed between the cation and the anion.

tetra-n-butyl ammonium hydroxide was used as a catalyst for one-pot, three component condensation reactions consisting of aromatic aldehydes, malononitrile and barbituric acid in ethanol:water solvent system at 60oc. current method has major advantages like mild reaction conditions with simple operation, high yields, by using a less toxic and lower costlier catalyst.in conclusion, we have explo...

The paper presents the design and simulation of double spiral Pt-based microhotplate (MHP) for gas sensing application. A platinum resistor of 52 Ω has been designed and simulated on a 0.3 micron thick SiO2 suspended membrane of size 40 × 40 μm using ANSYS. The SiO2 membrane of size 40 × 40 μm and thickness 0.3 micron has been fabricated successfully by bulk micromachining in <100> orientation ...

A novel surface micromachining process is reported for aluminum nitride (AlN) thin films to fabricate piezoelectric unimorph suspension devices for micro actuator applications. Wet anisotropic etching of AlN thin film is used with a Cr metal mask layer in the microfabrication process. Tetra methyl ammonium hydroxide (TMAH) of 25 wt.% solution is used as an etching solution for the AlN thin film...

   We report an investigation on the synthesis of Copper Oxide nanostructures via the Electro-Explosion of Wire method. Cu-CuO and Cu-Cu2O nanoparticles with mean particle size of 21.1 to 59.1 nm were synthesized by changing the applied current density and amount of used Tetra Methyl Ammonium Hydroxide as the surfactant. The X-ray diffraction analysis, field emission scanning ele...

The asymmetric unit of the title compound {(C6H18N2)2[Sb2Br10]·H2O} n , consists of two tetra-methyl-ethylendi-ammonium cations that are located on centres of inversion, as well as one tetra-methyl-ethylendi-ammonium cation, one water mol-ecule, one distorted octahedral [SbBr6](3-)anion and one bisphenoidal [SbBr4](-) anion in general positions. The [SbBr6](3-) and [SbBr4](-) anions are linked ...

The title compound, [1-(CH(3))(3)NCH(2)-1,2-C(2)B(10)H(11)](+)·I(-) or C(6)H(22)B(10)N(+)·I(-), was obtained by the reaction of (1,2-dicarba-closo-dodeca-boran-yl)dimethyl-methanamine with methyl iodide. The asymmetric unit contains two iodide anions and two (o-carboran-yl)tetra-methyl-ammonium cations. The bond lengths and angles in the carborane cage are within normal ranges, but the N-C(meth...

The title compound, (CH(6)N)(2)[WS(4)], was synthesized by the reaction of ammonium tetra-sulfidotungstate(VI) with aqueous methyl-amine. The title compound is isotypic with the corresponding Mo analogue (CH(6)N)(2)[MoS(4)], and its structure consists of a slightly distorted tetra-hedral [WS(4)](2-) dianion and two crystallographically independent methyl-ammonium (MeNH(3)) cations, all of which...

In the title compound, (CH(3))(4)N(+)·0.5C(8)H(4)O(4) (2-)·2H(2)O, the complete terephthalate dianion is completed by twofold symmetry and has a dihedral angle of 23.5 (2)° between the carboxyl-ate group and its parent ring. Two independent water mol-ecules serve as both donors and acceptor in the construction of undulating hydrogen-bonded host layers with various O-H⋯O contacts ocurring betwee...
