The title compound, C(15)H(21)NO(2)S, synthesized by N-alkyl-ation of cyclo-hexyl-amine benzene-sulfonamide with allyl iodide, is of inter-est as a precursor to biologically active sulfur-containing heterocyclic compounds. The cyclo-hexane ring is in a chair form and its mean plane makes a dihedral angle of 53.84 (12)° with the phenyl ring.

In the title compound, C(15)H(16)N(2)O(4)S, there is a dihedral angle of 63.30 (8)° between the nitro-benzyl and benzene rings, which are separated by a sulfonamide unit The crystal packing is stabilized by a C-H⋯O inter-action.

In the title compound, C11H15ClN2O3S, the 3-chloro-2,2-dimethyl-propanamide and sulfonamide substituents are arranged on opposite sides of the benzene ring plane. In the crystal, mol-ecules are linked by N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional network.

We report the synthesis and characterization of the pyrrole sulfonamide as a new class of potential molecular receptors, including conformational analysis and molecular recognition studies for four pyrrole sulfonamide derivatives.

Stability constant (log ) and thermodynamic parameters of Cd complexes with sulfonamide and cephapirin were determined by Polarographic technique at pH = 7.30 ± 0.01 and μ = 1.0 M KNO3 at 250°C. The sulfonamides were sulfadiazine, sulfisoxazole, sulfamethaxazole, sulfamethazine, sulfathiazole, sulfacetamide and sulfanilamide used as primary ligands and cephapirin as secondary ligand. Cd formed ...

The nine-membered fused-ring system of the title pyridazine derivative, C(13)H(12)N(4)O(4)S, is approximately planar (r.m.s. deviation 0.027 Å), and the benzene ring of the phenyl-sulfamide substituent is aligned at 43.5 (1)° to the fused-ring system. The amine group of the sulfonamide substituent forms an N-H⋯O hydrogen bond to the ketonic O atom of two neigboring mol-ecules to generate a chai...

In the title centrosymmetric dinuclear complex, [Cu(2)(C(15)H(11)BrN(2)O(3)S)(2)(C(2)H(6)OS)(2)], the Cu(II) ion is N,O-chelated by a dianionic ligand, monocoordinated by the sulfonamide N atom of a symmetry-related ligand and coordinated by an O atom from a dimethyl sulfoxide ligand, forming a distorted square-planar coordination geometry.

Interand intra-molecular forces are the driving forces responsible for the creation of an interface between a microorganism and a naturally occurring mineral or man-made material. We have used atomic force microscopy to directly measure forces between a Staphylococcus aureus bacterium and each of two materials (silica and polystyrene) in an electrolyte solution. Force “spectra” were collected b...
