In the title complex, [Cd(C(6)H(4)N(3)O(3)S)(2)(C(12)H(8)N(2))(2)]·2H(2)O, the Cd(2+) cation is located on an inversion center and is coordinated by four N atoms from two symmetry-related 1,10-phenanthroline ligands and two sulfonate O atoms from two benzotriazole-7-sulfonate anions, displaying a distorted CdN(4)O(2) octa-hedral geometry. In the crystal, O-H⋯N, O-H⋯O, N-H⋯O, C-H⋯N and C-H⋯O hyd...

The title compound, [Fe(CF(3)O(3)S)(C(36)H(44)N(4))], is an iron(III) porphyrin complex with the trifluoro-methane-sulfonate anion as an axial ligand. The Fe atom is displaced by 0.219 (2) Å toward the trifluoro-methane-sulfonate anion from the 24-atom mean plane of the porphyrin, resulting in a distorted FeN(4)O square-based pyramidal geometry. One ethyl-ene group is disordered over two orient...

Crystal structure of zwitterionic trimethylammoniopropane sulfonate (Z1-Methyl) was determined by single-crystal X-ray diffractometry. Z1-Methyl crystallized in the monoclinic system, space group P2(1), with a = 6.3639(2), b = 10.9237(4), c = 8.1505(4) A, beta = 111.078(2) degrees, V = 528.69(4) A3, Z = 2. An inter-molecular ionic association was observed in the crystal. The shortest distance b...

The inhibitory effect of sodium polyanethol sulfonate (0.05%) upon growth of Neisseria meningitidis was found to be neutralized by adding gelatin (l.1%) to the growth medium. The neutralizing effect was demonstrated in solid medium, as well as in nutrient broth for blood cultures. The findings parallel those of Wilkins and West (6) regarding gelatin neutralization of the inhibitory effect of so...

The title compound, [Fe(CF(3)O(3)S)(C(48)H(36)N(4)O(4))], is a five-coordinate iron(III) porphyrin complex with a trifluoro-methane-sulfonate anion as an axial ligand. The Fe(III) atom is displaced by 0.40 (1) Å towards the trifluoro-methane-sulfonate anion from the 24-atom mean plane of the porphyrin. The average Fe-N(p) distance is 2.044 (2) Å and the Fe-O distance is 2.001 (2) Å.

The imino-diacetic acid component of the title salt, C(4)H(8)NO(4) (+)·C(7)H(7)SO(3) (-), is protonated at the N atom. The cation uses the ammonium group to form hydrogen bonds to the O atoms of two adjacent sulfonate groups. In addition, the carboxylic acid portions of the cation form hydrogen bonds to the sulfonate groups. The hydrogen-bonding inter-actions give rise to a layer structure.

For almost a century, various predictions have been made that the human race was imminently going to run out of available petroleum. The passing of time has proven all those predictions to have been utterly wrong. It is pointed out here how all such predictions have depended fundamentally upon an archaic hypothesis from the 18th century that petroleum somehow (miraculously) evolved from biologi...

Chimeric plasmids containing the uvsY uvsW region of the T4 genome were examined for the expression of these genes. Certain of these plasmids were shown to express the uvsY or the uvsW gene products by their ability to complement the UV sensitivity of infecting uvsW or uvsY mutant phage. Also, a chimeric plasmid containing both the uvsW and uvsY genes increases the survival of UV-irradiated, me...

Extraction of dilute metal ions from water was performed near room temperature with a variety of ionic liquids. Distribution coefficients are reported for fourteen metal ions extracted with ionic liquids containing cations 1-octyl-4-methylpyridinium [4MOPYR], 1-methyl-1octylpyrrolidinium [MOPYRRO] or 1-methyl-1-octylpiperidinium [MOPIP], and anions tetrafluoroborate [BF4], trifluoromethyl sulfo...
