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.

Many quinolones, substituted quinolines and thiones are well known for their biological activity. The redox characteristics of such biological substances may provide valuable information about the redox behaviour in living systems. The present paper is aimed at carrying out a methodical cyclic voltammetric investigation of the peak potential values of 4-methyl/phenyl -3vinyl quinoline-2(1H) one...

In this research, Montmorillonite clay nanoparticles were produced using mechanical methods and the effect of different percentages of tetra n-butyl ammonium chloride (TNBAC) as a surfactant and butyl ammonium chloride as a modifier (TNBAC) was performed. The microstructural and morphological properties of montmorillonite clay nanoparticles in the presence and absence of surfactant as well as s...

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, C20H29NSi(+)·Br(-), contains a chiral silicon atom but crystallizes as a racemate. The C-Si-C bond angles in the range of 103.64 (8)-111.59 (9)° are usual for tetra-hedral geometry. The piperidine ring shows a regular chair conformation with an equatorially positioned exocyclic N-C bond. In the crystal, there is a hydrogen bond between the ammonium cation and the bromide ani...
