the analysis of the 27al and 35cl quadrupole coupling parameters of aluminum methyl chloride dimers were carried out on the basis of the density functional theory (dft). the available experimental values of quarupole coupling constants were compared with their calculated ones. in this investigation, the correlations were made between calculated 27al and 35cl nuclear quadrupole coupling constant...

It is well known that mercury is ac cumulated in the kidney and causes renal failure. Mercury has been a subject of extensive study, but a definite mechanism for its biochemical toxicity remains to be elucidated. In a previous paper (1), we reported that mersalyl (mercurial diuretic) had a more powerful stimulatory effect on the lipid peroxidation in renal cortical mito chondria than any other ...

In the title salt, C14H20NO(+)·Cl(-), the piperidine ring adopts a chair conformation. In the crystal, the cations and anions are linked by classical N-H⋯Cl hydrogen bond and weak C-H⋯Cl and C-H⋯O hydrogen bonds; the C-H⋯O hydrogen bonds exhibit R 2 (2)(14) ring motifs while the C-H⋯Cl hydrogen bonds link the mol-ecules into chains along the a-axis direction. π-π stacking is observed between pa...

The title compound, C(9)H(8)N(3)O(+)·Cl(-), was isolated from a liquid culture of streptomyces sp. In the cation, the ring system makes a dihedral angle of 0.2 (2)° with the amide group. The protonation creating the cation occurs at ome of the N atoms in the quinoxaline ring system. In the crystal, the ions are linked through N-H⋯O and N-H⋯Cl hydrogen bonds, forming a two-dimensional network pa...
