Preparation and Characterization of some Transition Metal Complexes with OleylXanthate and 1,10- Phenanthrolin

Abstract

Xanthatecomplexes of the general formula [M{Ag(oleylXant) 2 } 2 ] (A) and [MM'(oleylXant) 4 ] (B) were M = Copper (II), Nickel II), Cobalt (II) M' = Cadmium(II), Zinc(II). These complexes were reacted with bidentatelewis base (1,10-phenanthroline). The result of this reaction gave the complexes [M(phen)][{Ag(oleylxant) 2 } 2 ] (I.A) and [M(phen)][M'(oleyl-xant) 4 ] (I.B), which have been prepared and measured by an infrared, magnetic suscetptibility measurements, conductance measurements, electronic spectra and elemental analysis electronic absorption spectra. These data indicate gave the result that the complexes of the type (A & B) are a square planer geometry while the complexes of the type (I.A), (I.B) have an octahedral geometry.

Synthesis of Nickel Sulfide Thin Films and Nanocrystals from the Nickel Ethyl Xanthate Complex

“…It has two polymorphs: α-NiS (hexagonal), which is stable at high temperatures (>379), and a rhombohedral β-NiS which is also stable at lower temperatures [28,29]. NiS thin films and nanoparticles with varying stoichiometries (NiS, NiS 2 , Ni 3 S 2 , Ni 3 S 4 , Ni 6 S 5 , Ni 7 S 6 , Ni 4 S 3+x , Ni 3+x S 2 , and Ni 9 S 8 ) and nanostructures have been prepared using various starting materials and precursors [21,30,31]. Some methods used to synthesize nickel sulfide include thermal decomposition, hydrothermal treatment, and solvothermal methods [32,33].…”
