In the title complex, [Cu(C(15)H(19)N(2))(2)] or [Cu(L(2))] (HL is 3,3',4,4',5,5'-hexa-methyl-pyrromethene), the Cu(II) atom is coordinated by four N atoms [Cu-N 1.939 (2)-1.976 (2) Å] from two L ligands in a distorted tetra-hedral geometry. The mean planes of the CuN(2)C(3) metallocyclic rings form a dihedral angle of 72.73 (6)°. In the L ligands, the pyrrole rings are inclined to each other a...

In the title compound, [Cu(NO(3))(2)(C(19)H(15)N(3)O(2))], the coordination geometry around the Cu(II) ion can be described as distorted square-pyramidal, with two N atoms and one O atom from an (E)-4-hy-droxy-N'-[phen-yl(pyridin-2-yl)methyl-ene]benzohydrazide ligand and one nitrate O atom in the basal plane and one nitrate O atom at the apical site. The other two nitrate O atoms also bind to t...

The title compound, [Cu(C(5)H(5)N)(2)(C(18)H(15)P)(2)]BF(4), crystallizes as discrete [(PPh(3))(2)(py)(2)Cu](+) cations and [BF(4)](-) anions and is isostructural with the analogous perchlorate salt. The anion is located in close proximity to the pyridine ligands with weak C-H⋯F inter-actions apparent. The P(2)CuN(2) coordination geometry is pseudo-tetra-hedral, with P-Cu-P and N-Cu-N angles of...

Multi-walled carbon nanotubes (MWNTs)/Cu-doped ZnO composite powders were prepared by co-precipitation method, and were characterized by X-ray diffraction, electron microscopy, fluorescence spectrum, and ultraviolet spectrum. Experimental results show that the MWNTs can be modified by Cu-doped ZnO nanoparticles with hexagonal wurtzite structure after annealed at 450 °C, and the nanoparticle siz...

In the title complex, [CuCl(2)(C(15)H(14)N(4)O)], the Cu(II) atom possesses a highly distorted square-planar geometry with N-Cu-N and Cl-Cu-Cl angles of 79.86 (8) and 98.65 (3)°, respectively, while the Cl-Cu-N angles fall into two distinct groups with values of 95.26 (6), 98.75 (6), 150.56 (6) and 152.04 (6)°. The pyridyl ring is twisted by 9.4 (2)° with respect to the triazole ring, which is ...

This study was conducted to examine whether Cu could exert its growth-promoting effect when injected, rather than being fed, and thus bypass the gastrointestinal tract. In two 18-d experiments, pigs were injected every 2 d with a Cu histidinate or histidine solution. Amounts of Cu injected were calculated to simulate varying absorption rates in pigs fed 250 ppm of dietary Cu. In Exp. 1, 44 pigs...

The title compound, [Cu(C(8)H(7)O(3))(2)(C(10)H(8)N(2))]·H(2)O, is comprised of a Cu(II) ion, two 3-meth-oxy-benzoate ligands, a 2,2'-bipyridine (bipy) ligand and one uncoordinated water mol-ecule. The Cu(II) ion and the water O atom lie on a twofold axis. The Cu(II) ion exhibits a six-coordinate distorted octa-hedral geometry, with two N atoms from the bipy ligand [Cu-N = 1.9996 (16) Å] and fo...

The asymmetric unit of the title compound, {[Cu(C(13)H(15)NO(3))(C(5)H(8)N(2))]·CH(3)OH}(n), contains two complex mol-ecules and two solvent mol-ecules. Each Cu(II) ion is in a distorted square-pyramidal coordination with one N and two O atoms from the Schiff base ligand and one N atom from the heterocycle in the basal positions and one carboxyl-ate O atom from a neighbouring ligand in the apic...

Composition space diagrams have been used to study phase stability of mixed transition metal oxide fluorides synthesized by hydrothermal reaction of the metal oxides in (HF)(x)().pyridine/H(2)O/pyridine solution (150 degrees C, autogenous pressure). The combination of early (Ti, Zr, Hf, Nb, Ta, Mo, W) and late (Cu, Cd, Zn) transition metals and the effects of varying the mole ratios of the meta...
