The crystal structure of the title compound, [Cu2(C18H12Br2N4O2S2)2], consists of binuclear complex units which lie across inversion centres and are connected by weak Cu-O coordination bonds forming chains along the b axis. The CuII ion is five-coordinated by two N atoms and two O atoms of the chelating ligand and one symmetry-related O atom forming a square-pyramidal coordination geometry. In ...

In this article, from the tunnels that infect underground part of vegetable crops: turnip moth (Agrotis segetum Den.et Schiff), cut worm (A. exclamationis. L.), turn black-C (Xestia c-nigrum wild (Euxoa agricola V.), gamma (Mamestra suasa Schiff.), tobacco obesa B.) and epsolon ipsilon Rotl) encounter was detected. Underground cutworms damage to tomatoes is estimated at 6-10% in Navoi, Bukhara ...

In the title Schiff base compound, C(15)H(15)NO(2), prepared from 4-meth-oxy-benzyl-amine and salicyl-aldehyde, an intra-molecular O-H⋯N hydrogen bonds influences the mol-ecular conformation; the two aromatic rings form a dihedral angle of 73.5 (1)°. In the crystal, weak inter-molecular C-H⋯O inter-actions link the mol-ecules into chains propagating in [010].

The title Schiff base compound, C(15)H(15)N(3)O(4), was prepared from a condensation reaction of 3-eth-oxy-4-hydroxy-benz-aldehyde and 3-nitro-phenyl-hydrazine. The mol-ecule is nearly planar; the dihedral angle between the hydroxy-benzene ring and the nitro-benzene ring is 6.57 (7)°. O-H⋯O, O-H⋯N and C-H⋯O hydrogen bonding helps to stabilize the crystal structure.

The title compound, C(15)H(15)N(3)O(4), a Schiff base, was obtained from a condensation reaction of 3-eth-oxy-4-hydroxy-benzaldehyde and 2-nitro-phenyl-hydrazine. The mol-ecule is approximately planar, the largest deviation from the mean plane being 0.1449 (16) Å. An intramolecular N-H⋯O inter-action is also present. In the crystal, inter-molecular O-H⋯O hydrogen bonds link the mol-ecules, form...

Ribonuclease A has been used as a model protein for studying the specificity of glycation of amino groups in protein under physiological conditions (phosphate buffer, pH 7.4, 37 degrees C). Incubation of RNase with glucose led to an enhanced rate of inactivation of the enzyme relative to the rate of modification of lysine residues, suggesting preferential modification of active site lysine resi...

Die CuI-Salze [Cu(CH3CN)4]PF und [Cu(oDFB)2]PF mit dem sehr schwach koordinierenden Anion Al(OC(CF3)3)4− (PF), sowie [Cu(NEt3)2]PF einzigartigen, linearen Bis-Triethylamin-Komplex [Cu(NEt3)2]+ wurden synthetisiert als Katalysatoren für die Umwandlung von Monophenolen zu o-Chinonen untersucht. Aktivitäten dieser bei der Monooxygenierung 2,4-Di-tert-butylphenol (DTBP-H) denen [Cu(CH3CN)4]X-Salze ...
