In the title compound, C(12)H(12)Cl(2)N(2) (2+)·SO(4) (2-), the two rings are not coplanar [dihedral angle = 48.7 (2)°]. In the crystal, multiple N-H⋯O hydrogen-bond inter-actions are found between the ammonium and sulfate groups.

In the crystal structure of the title compound, 2C(5)H(5)N(4)O(+)·SO(4) (2-), N-H⋯O hydrogen bonds assemble the mol-ecules into a two-dimensional network structure parallel to the cb plane. The S atom of the sulfate ion lies on a special position on a twofold axis.

Sulfate-reducing bacteria, like Desulfovibrio vulgaris Hildenborough, use the reduction of sulfate as a sink for electrons liberated in oxidation reactions of organic substrates. The rate of the latter exceeds that of sulfate reduction at the onset of growth, causing a temporary accumulation of hydrogen and other fermentation products (the hydrogen or fermentation burst). In addition to hydroge...

In the cerate(IV) anion of the title salt, (C(2)H(10)N(2))(5)[Ce(2)(SO(4))(9)]·3H(2)O, the two metal atoms are bridged by three sulfate units; each metal atom is itself chelated by other three sulfate units so that the metal atoms exist in nine-coordinate tricapped trigonal-prismatic geometries. The anions, cations and uncoordinated water mol-ecules are linked by O-H⋯O and N-H⋯O hydrogen bonds,...

The crystal structure of the title salt {systematic name: [1,3-phenyl-enebis(methyl-ene)]bis-(aza-nium) sulfate}, C8H14N2 (2+)·SO4 (2-), consists of infinite (100) sheets of alternating organic and inorganic entities The m-xylylenediaminium cations are linked to the sulfate anions by N-H⋯O and asymmetric bifurcated N-H⋯(O,O) hydrogen bonds, generating a three-dimensional network. A weak C-H⋯O i...

In the title compound, [Zn(SO(4))(C(12)H(8)N(2))(2)]·C(3)H(8)O(2), the Zn(2+) ion (site symmetry 2) is coordinated by two chelating 1,10-phenanthroline ligands and an O,O'-bidentate sulfate ion (S site symmetry 2), resulting in a distorted cis-ZnO(2)N(4) octa-hedral geometry for the metal ion. The complete propane-1,3-diol mol-ecule is generated by crystallographic twofold symmetry and two O-H⋯...

In the crystal structure of the title salt, 2C(5)H(6)NO(+)·SO(4) (2-)·H(2)O, one planar (r.m.s. deviation = 0.01 Å) cation is stacked approximately over the other [dihedral angle between planes = 8.6 (1)°]. The pyridinium and hydr-oxy H atoms are hydrogen-bond donor atoms to the O atoms of the sulfate anion; the cations, anions and water mol-ecules are consolidated into a three-dimensional netw...

In the title compound, 2C(6)H(7)N(2)O(2) (+)·SO(4) (2-)·3H(2)O, there are two independent cations which are connected into N-H⋯O hydrogen-bonded dimers. In the crystal, O-H⋯O hydrogen-bonded sulfate-water sheets run parallel to (001) and are linked into a three-dimensional network via inter-molecular N-H⋯O and O-H⋯O hydrogen bonds through the 2-amino-nicotinium dimers. Further stabilization is ...

Objective(s) The aims of present study were to elucidate the effect of NaHS as a H2S donor on precontracted rat trachea smooth muscle, role of epithelium and nitric oxide in this action. Materials and Methods Tracheal rings from male adult Wistar rats were isolated and mounted in an organ bath containing Krebs–Henseleit solution under 1.5 g resting tension and contractions were recorded isom...

The asymmetric unit of the title compound, C(16)H(17)ClNO(2)S(+)·HSO(4) (-), (I) [systematic name: (+)-(S)-5-[(2-chloro-phen-yl)(meth-oxy-carbon-yl)meth-yl]-4,5,6,7-tetra-hydro-thieno[3,2-c]pyridin-5-ium hydrogen sulfate], contains two independent cations of clopidogrel and two independent hydrogensulfate anions. The two independent cations are of similar conformation; however, this differs fro...
