THE ASYMMETRIC UNIT OF THE TITLE SALT [SYSTEMATIC NAME: 1-benzhydryl-4-cinnamylpiperazine-1,4-diium bis-(p-toluene-sulfonate) dihydrate], C26H30N2 (2+)·2C7H7O3S(-)·2H2O, consists of a diprotonated cinnarizinium cation hydrogen bonded through two water mol-ecules to two independent p-toluene-sulfonate anions, one which is disordered over two sets of sites in a 0.793 (3):0.207 (3) ratio. In the c...

There are three Ag(I) cations, three p-toluene-sulfonate (pts) anions, three hexa-methyl-ene-tetra-mine (hmt) mol-ecules and four water mol-ecules in the asymmetric unit of the title coordination polymer, {[Ag(3)(C(7)H(7)O(3)S)(3)(C(6)H(12)N(4))(3)(H(2)O)]·3H(2)O}(n). Two of the pts anions show positional disorder of their O atoms in 0.60:0.40 and 0.50:0.50 ratios. The Ag(I) ion is coordinated ...

In the title mol-ecule (systematic name: methane-tetra-yltetra-methyl-ene tetra-p-toluene-sulfonate), C(33)H(36)O(12)S(4), the central C atom and the S atoms exhibit distorted tetra-hedral configurations. The aromatic rings in opposite arms are nearly parallel to each other, with a dihedral angle of 10.26 (8) or 3.45 (9)°. The mol-ecules are linked into a two-dimensional network parallel to the...

Among 67 patients with rheumatoid arthritis treated with gold salts (aurothiopropanol sulphonate) a significant correlation (p less than 10(-2)) was noted between gold toxic reactions, whatever their type, and the HLA antigens A1, B8, Cw7, and DR3. Forty-two patients were genotyped, and a correlation was observed between gold side effects and the haplotype A1 Cw7 B8 DR3 (p less than 10(-2), RR ...

The crystal structure of the title compound, C(7)H(10)N(+)·C(7)H(7)O(3)S(-), displays strong N-H⋯O and N-H⋯S hydrogen bonding between the ammonium group and the p-toluene-sulfonate anion, linking the cations and anions into chains along the b axis.

A facile, dissolution-free route to direct synthesis of hexagonal magnesium hydroxide nanoplates from natural brucite is reported. Stable brucite undergoes disaggregation into thin nanosheets and subsequent solid-solid transformation in the presence of p-toluene sulfonate, circumventing the threshold of size effect from bulk brucite to Mg(OH)(2) nanoplates.

In the title salt, C(6)H(10)N(3)O(2) (+)·C(7)H(7)O(3)S(-), the 2-amino-4,6-dimeth-oxy-pyrimidinium cation inter-acts with the sulfonate group of the p-toluene-sulfonate anion via a pair of N-H⋯O hydrogen bonds, forming a cyclic hydrogen-bonded R(2) (2)(8) motif, which in the crystal is linked by further intemolecular N-H⋯O hydrogen bonds, forming supra-molecular chains along the c axis. Further...

Pseudomonas putida F1 and Pseudomonas sp. strain JS150 initiate toluene degradation by incorporating molecular oxygen into the aromatic nucleus to form cis-1,2-dihydroxy-3-methylcyclohexa-3,5-diene. When toluene-grown cells were incubated with 2- and 3-nitrotoluene, the major products identified were 2- and 3-nitrobenzyl alcohol, respectively. The same cells oxidized 4-nitrotoluene to 2-methyl-...

In the title hydrated mixed-cation salt, (C(5)H(8)N(3))(2)[Co(H(2)O)(6)](SO(4))(2)·2H(2)O, the complete octa-hedral hexa-aqua complex cation is generated by crystallographic inversion symmetry. In the crystal, the components are linked by O-H⋯O and N-H⋯O hydrogen bonds, the latter, involving pyrimidinium cations and sulfate anions, generating R(2) (2)(8) loops. These, together with π-π inter-ac...
