The structure of the title compound, C(11)H(19)NO(4), contains two crystallographically independent mol-ecules in the asymmetric unit. Both adopt the same conformation and they form pseudosymmetric R(2) (2)(8) dimers via two N-H⋯O hydrogen bonds. The dimers are linked by weak C-H⋯O inter-actions and are stacked in columns along the a axis.

We isolated three Sphingobium fuliginis strains from Phragmites australis rhizosphere sediment that were capable of utilizing 4-tert-butylphenol as a sole carbon and energy source. These strains are the first 4-tert-butylphenol-utilizing bacteria. The strain designated TIK-1 completely degraded 1.0 mM 4-tert-butylphenol in basal salts medium within 12 h, with concomitant cell growth. We identif...

In the mol-ecule of the title compound, C(12)H(15)BrN(4)O(2), the imidazole and pyridine rings are strictly coplanar [maximum deviation 0.006 (3) Å]. In the crystal structure, mol-ecules are linked into chains running parallel to the a axis by inter-molecular N-H⋯O hydrogen bonds. Centrosymmetrically related chains are further connected by N-H⋯N hydrogen-bonding inter-actions to form a two-dime...

In the crystal structure of the title compound, C16H24N4O4, mol-ecules are linked by N-H⋯O hydrogen bonds between the carbonyl groups of the carbamoyl and amido functional groups and the amino groups, and by N-H⋯N hydrogen bonds between the amino group and the pyridine ring, forming two-dimensional networks parallel to the ab plane.

The mol-ecule of the title compound, C(16)H(23)N(3)O(5), is twisted about the chiral C atom, the dihedral angle formed between the amide residues being 79.6 (3)°. The conformation about the imine bond [1.278 (5) Å] is E. In the crystal, O-H⋯O and N-H⋯O hydrogen bonding between the hy-droxy, amine and carbonyl groups leads to the formation of supra-molecular layers, which stack along the c-axis ...

The title compound, C(11)H(21)Cl(3)N(2)O(4)S, was produced as part of a development programme of a new synthetic route to chloro-ethyl-nitro-sosulfamides (CENS) with three chloro-ethyl moieties. These compounds possess structural features that confer potential biological activity and act as alkyl-ating agents. The packing is governed by four weak C-H⋯O inter-actions, forming an infinite three-d...

In the crystal of the title compound, C(17)H(20)N(2)O(2), the molecules are linked by C-H⋯O interactions. Intra-molecular C-H⋯O and N-H⋯N hydrogen bonds also occur.

In the title hydrate, C(19)H(25)N(3)O(3)S·H(2)O, the configuration at each chiral centre in the organic mol-ecule is S, with the hy-droxy and carbamate substituents being anti [O-C-C-N torsion angle = -179.3 (3)°]. The thio-pyrimidyl and carbamate residues lie to one side of the pseudo-mirror plane defined by the C(5)S backbone of the mol-ecule; this plane approximately bis-ects the benzene rin...

The mol-ecule of the title ethanol solvate, C(15)H(21)N(3)O(6)·C(2)H(6)O, adopts a curved shape; the conformation about the imine bond [N=N = 1.287 (3) Å] is E. The amide residues occupy positions almost orthogonal to each other [dihedral angle = 85.7 (2)°]. In the crystal, a network of O-H⋯O, O-H⋯N and N-H⋯O hydrogen bonds leads to the formation of supra-molecular arrays in the ab plane with t...
