The title compound, (C(6)H(8)N(4))[Mn(H(2)O)(6)](SO(4))(2), was obtained by cocrystallization of 2,2'-biimidazolium sulfate and bis-(tetra-butyl-ammonium) tetra-chlorido-manganate(II). The asymmetric unit contains one isolated (SO(4))(2-) anion, one half of an octa-hedral [Mn(H(2)O)(6)](2+) dication and one half of a 2,2'-biimidazolium dication, each of which lies on an inversion centre. Mol-ec...

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...

Via the one-pot condensation reaction of ethyl acetoacetate, aromatic aldehydes, 2,4-dinitrophenylhydrazine, and β-naphthol; new pyrazolone derivatives were synthesized in the presence of three Brønsted acid catalysts. These Brønsted acid catalysts are Silica sulfuric acid (SSA), tetra-n-butyl ammonium hydrogen sulfate (TBAHSO4) and [2,2′-Bipyridine]-1,1′-diium tricyanomethanide {[2,2′-BPyH][C(...

In the title compound, (C(16)H(36)N)[Fe(C(12)H(8)N(3)O(2))(CN)(3)]·2H(2)O, the tetra-n-butyl-ammonium ion has a tetra-hedral configuration around the N atom, while the Fe(III) atom of the tricyanido[N-(2-pyridyl-carbon-yl)pyridine-2-carboximidato]iron(III) anion adopts a distorted octa-hedral geometry. O-H⋯O and O-H⋯N hydrogen bonds link the components in the crystal structure.

In the title compound, (C(10)H(24)N)[FeCl(4)], no classical hydrogen bonds are observed. The butyl-triethyl-ammonium cations inter-act with the tetra-hedral [FeCl(4)](-) anion through weak C-H⋯Cl inter-actions, forming a three-dimensional network.

In the crystal structure of the title salt, C16H36N(+)·CH3BN(-), the tetra-n-butyl-ammonium cations and [BH3(CN)](-) anions are connected via weak C-H⋯N inter-actions, forming chains along the b-axis direction. The anion is almost linear with an N-C-B angle of 178.7 (2)°. The C-N-C angle values at the core of the tetra-n-butyl-ammonium cation range from 105.74 (11) to 111.35 (11)° with an avera...

cis-polybutadiene was functionalized using in–situ generated dmd as oxidant and tetra-n-butyl ammonium bromide as phase transfer catalyst (ptc). the epoxidation process was investigated by 1hnmr spectroscopy. 1hnmr spectrum analysis of products confirms the absence of ring opening side products in epoxidation reaction. various factors such as reaction temperature, reaction time and the concentr...

In the title compound, [N(C4H9)4][Sn(C4H9)Cl4], the Sn(IV) atom of the stannate anion has a trigonal-bipyramidal coordination sphere by two Cl atoms and one butyl chain in the equatorial plane and by two Cl atoms in the apical positions. Two of the four butyl chains of the tetra-butyl-ammonium cation are partially disordered, each with refined site occupancies of 0.691 (6):0.309 (6). Weak C-H⋯C...

The title compound, [Co(C(10)H(21)N(2))Cl(3)], was obtained as the by-product of the attempted synthesis of a cobalt sulfate framework using 1,4-diaza-bicyclo-[2.2.2]octane as an organic template. The asymmetric unit comprises two distinct mol-ecules, and in each, the cobalt(II) ions are tetra-hedrally coordinated by three chloride anions and one 1-butyl-diaza-bicyclo-[2.2.2]octan-1-ium cation....
