Mono and bis hexamethylenetetramine iron(III) chloride, Fe(N C ,H ) CI (I) and Fe(N C ,H ) Cl (II) were synthesized by the reaction of iron(III) chloride and hexamethylenetetramine (HMTA) in chloroform. Chemical analysis and spectral results show the coordination of HMTA to the iron(III). Electronic transition spectra of compound I and I1 were also studied in coordinating and noncoordinatin...

The reactions of 1 - chloro - 2 - nitro benzene with 2 - Amino thio phenol yield the 2 - ( ( nitro phenyl ) thio ) aniline and then 2 , 2' - thio dianiline of this compound was prepared . Also the symmetrical potentially pentadentate N 2 O 2 S Schiff base ligand 2 , 2' - ( ( ( thio bis (1 , 2 - phenylene ) ) bis ( azanilidene ) ) bis ( methenilidene ) ) diphenol ( H 2 L ) obtain by added salicy...

The complete mol-ecule of the title compound, [Cd(C(6)H(12)NOS(2))(2)(C(12)H(10)N(4))(2)], is generated by crystallographic inversion symmetry. The distorted octa-hedral trans-N(2)S(4) donor set for the Cd(2+) ion is defined by two symmetrically S,S'-chelating dithio-carbamate anions and two pyridine N atoms derived from two monodentate 4-pyridine-aldazine (or 4-{[(pyridin-4-yl-methyl-idene)hyd...

Pyridinium 2-carboxylates decompose thermally in the presence of a variety of late transition metal precursors to yield the corresponding 2-pyridylidene-like complexes. The mild reaction conditions and structural diversity that can be generated in the heterocyclic ring make this method an attractive alternative for the synthesis of 2-pyridylidene complexes. IR spectra of the Ir(i) carbonyl comp...

The title compound, dizinc cadmium hydroxide tetraoxido-vanadate, Zn(1.86)Cd(0.14)(OH)VO(4), was prepared under low-temperature hydro-thermal conditions. It is isostructural with Zn(2)(OH)VO(4) and Cu(2)(OH)VO(4). In the crystal structure, chains of edge-sharing [ZnO(6)] octahedra are inter-connected by VO(4) tetra-hedra (site symmetries of both V atoms and their coordination polyhedra are .m.)...

Single-source molecular precursors were used to synthesize II-VI compound semiconductor nanowires for the first time. Cadmium sulfide and zinc sulfide nanowires were prepared using cadmium diethyldithiocarbamate, Cd(S2CNEt2)2, and zinc diethyldithiocarbamate, Zn(S2CNEt2)2, respectively, as precursors in a gold nanocluster-catalyzed vapor-liquid-solid growth process. High-resolution transmission...

Schiff bases are versatile ligands and known to be synthesized from the condensation of an amino compound with carbonyl compounds. These compounds along with their metal complexes are considered to be an important as catalysts in various biological processes. Also Schiff base complexes are gaining popularity among the various industries including polymers, dyes and pharmaceutical. This review s...

Within the realm of catalytic asymmetric hydrogenation, the focus continues to be on the use of chiral metal complexes in conjunction with a hydrogen source. Recently, the widespread development of organocatalysis, including the invention of iminium activation, has led to the discovery of many new enantioselective transformations. Based on this strategy, a number of bioinspired processes for th...

In the title compound, [Cd(C(14)H(14)N(3)O(2))(2)(CH(3)OH)(2)], each cadmium(II) center is six-coordinated by an N atom and an O atom of two 1,3-bis-(2-methoxy-phen-yl)triazene ligands and by the O atoms of two methanol mol-ecules. The distorted octa-hedral coordination geometry of the Cd atom has two N and two O atoms in the equatorial plane, and two O atoms in axial positions. The complex is ...

Cadmium salts were examined for their biological effects on ciliated respiratory epithelium in hamster tracheal explants. Cadmium chloride and cadmium acetate both caused significant decreases in ciliary motion when tested at 100 micrograms M and above. Reductions in relative ciliary activity were dose-dependent and were first demonstrable at 8-32 hr. The decreased ciliary motion was accompanie...
