In each of the two independent mol-ecules in the asymmetric unit of the title compound, [Cu(C(13)H(15)NO(3))(C(3)H(4)N(2))], the Cu(II) atom is four-coordinated by two O atoms and the N atom of the tridentate Schiff base ligand and one N atom from the imidazole ligand in a distorted square-planar geometry. In the crystal structure, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds.

The title copper(I) salt, (C(15)H(14)N(2))[Cu(NCS)(3)], exists as non-inter-acting cations and trigonal-planar anions. The cation is buckled, the r.m.s. deviation of the atoms passing through the phenanthroline portion being 0.16 Å. The Cu(I) atom is displaced by 0.019 (2) Å out of the N(3) triangle. The crystal studied was a non-merohedral twin with twin domains in an approximate ratio of 55:45.

In the title compound, [Cu(C(17)H(15)NO(3))(C(3)H(4)N(2))], the Cu(II) atom is four-coordinated by two O atoms and the N atom of the tridentate Schiff base ligand, and one N atom from the imidazole ligand in a distorted square-planar geometry. In the crystal structure, mol-ecules are linked into dimers by inter-molecular N-H⋯O hydrogen bonds.

In the title complex, [Cu(C(16)H(15)NO(3))(C(10)H(8)N(2))]·3H(2)O, the Cu(II) atom is five coordinated by O,N,O'-donor atoms of the Schiff base ligand and by two N atoms of the 2,2'-bipyridine ligand in a distorted square-pyramidal geometry. In the crystal, mol-ecules are linked into a two-dimensional network parallel to (011) by O-H⋯O hydrogen bonds.

The elemental composition (surface adsorbed and internalized fraction of Cu, Mo and P) in marine phytoplankton was first examined in cultures of the diatom Phaeodactylum tricornutum which were exposed to various levels of Cu concentrations ranging from 0.25 to 16 μmol/L with equivalent free [Cu2+] concentrations of 0.4-26 nmol/L. We observed an acceleration of algal growth rates (20-40%) with i...

Simultaneous recovery of copper and DCA from simulated MEUF concentrated stream was investigated. Effects of surfactant (DCA) and metal (copper) concentrations, surfactant to metal molar ratio (S/M ratio), electroplating voltage, EDTA concentration, solution pH, and salt concentration on metal recovery and current efficiency were studied. Electric voltage of -0.5 V was shown to be optimum opera...

In fish, environmental pollution is one factor that induces oxidative stress, and this can disturb the natural antioxidant defense system. Oxidative stress has been well characterized in vitro, yet the in vivo effects of metal-induced oxidative stress have not been extensively studied. In two experiments we examined the impacts of copper (Cu) on gene expression, oxidative damage, and cell oxida...

Mixed ligand copper(II) complexes, viz., [Cu(Br-SAA)(ImH)], [Cu(Br-SAA)(MeImH)], [Cu(Br-SAA)(EtImH)], [Cu(Br-SAA)(BenzImH)] and [Cu(Br-SAA)(MebenzImH)], where Br-SAA = 5-bromosalicylideneanthranilic acid, ImH = imidazole, MeImH = 2-methyl imidazole, EtImH = 2-ethyl imidazole, BenzImH = benzimidazole, MebenzImH = 2-methyl benzimidazole are synthesized and characterized by elemental analysis, mol...
