In the title mol-ecular salt, (C(6)H(16)N)(2)[CuCl(4)], the Cu(II) ion adopts an extremely distorted tetra-hedral coordination geometry. All the ammonium H atoms are involved in N-H⋯Cl hydrogen bonds, which serve to link the cations and anions into chains propagating along the c-axis direction.

The -SCH(2)CH(2)CH(2)CH(2)S- portion of the title compound, C(12)H(14)N(2)S(2), adopts an extended zigzag conformation. The angles at the tetra-hedral carbon atoms are marginally increased [113.63 (12)° and 111.38 (17)° for S-C-C and C-C-C respectively] from the idealized tetra-hedral angle. The mol-ecule lies on an inversion center located at the mid-point of the butyl chain. In the crystal, t...

In the title compound, {(NH(4))(2)[Zn(C(8)H(6)O(8))]·4H(2)O}(n), the asymmetric unit contains one ammonium cation, half of a butane-1,2,3,4-tetra-carboxyl-ate anion, one Zn(2+) cation and two water mol-ecules. The butane-1,2,3,4-tetra-carboxyl-ate ligand is located about an inversion centre at the mid-point of the central C-C bond. The Zn(2+) cation is situated on a twofold rotation axis and is...

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....

The carbon dots were prepared by the microwave method, and then TiO2 doped with was successfully synthesized hydrothermal method. Its structure investigated using TEM, XRD XPS. catalyst applied to degradation of lignin base solution (50 mg in 30 mL sodium hydroxide pH = 12) under ultraviolet light. It found that when mass ratio point 1.5:1, dosage 0.75 g/L, time 6 h, rate could reach more than ...

Hyoscine-N-butyl bromide is a widely used antispasmodic belonging to the belladonna alkaloid class of semisynthetic quaternary ammonium compounds. These compounds exert a spasmolytic action on the smooth muscles of the bile-gastrointestinal tract, genitourinary tract, salivary glands (xerostomia), and also on the visual apparatus - in particular, the irido-ciliary complex. As a consequence, the...

The title compound, [Al(CH(3))(2)(C(29)H(39)N(2)O(2))], exhibits disorder of one of the tert-butyl groups on the Schiff base ligand, where each methyl group is located over two sites, with occupancy factors of 0.57 (1) and 0.43 (1). The geometry around the Al(III) atom is distorted tetra-hedral, defined by two methyl groups, one N and one O atom from the Schiff base ligand.

An efficient, catalytic, diastereo- and enantioselective conjugate addition of N-(diphenylmethylene)glycine tert-butyl ester to β-aryl substituted enones was realized in the presence of 1 mol% of newly desired dinuclear N-spiro-ammonium salts, affording functionalized α-amino acid derivatives in 57-98% yields with high diastereoselectivity (up to 99:1 dr) and enantioselectivity (up to 96.5:3.5 ...

In the title compound {systematic name: cis-bis-[4-amino-N-(pyrimidin-2-yl)benzene-sulfonamidato-κ(2)N,N']bis-(butyl-amine-κN)copper(II) penta-hydrate}, [Cu(C(10)H(9)N(4)O(2)S)(2)(C(4)H(11)N)(2)]·5H(2)O or [Cu(sdz)(2)(ba)(2)]·5H(2)O [ba is butyl-amine and sdz = sulfadiazine(1-)], the copper(II) cation is six-coordinated by four N atoms of two sulfadiazine ligands and two N atoms of butyl-amine ...

High purity lead titanate nanopowders in tetragonal form have been successfully prepared bycitric acid gel method using lead nitrate and tetra-n-butyl titanate as Pb and Ti sourcesrespectively and citric acid as complexing reagent. The precursors were calcined at varioustemperatures ranging from 450 °C to 600 °C for 2 h. Fourier Transform InfraredSpectroscopy (FT-IR), X-ray diffraction (XRD) an...
