Vanadium(IV and V) Complexes ContainingSNO (Dithiocarbonylhydrazone; Thiosemicarbazone) Donor Sets

Bonding and structure trends of thiosemicarbazone derivatives of metals—An overview

“…However, for some metals, different starting materials have been used. For example, for the preparation of vanadium complexes, the starting materials [VOCl 2 (thf) 2 ] [72] and NH 4 VO 3 [73] have been used, and likewise Cr III complexes were formed by the reaction of CrCl 3 ·6H 2 O with a thiosemicarbazone in presence of solid NaHCO 3 in aqueous medium [74][75][76].…”

“…Ruthenium(II) complexes have been prepared from RuCl 2 (PPh 3 ) 3 [69][70][71][72][73][74], RuCl 2 (bipy) 2 [91], or Ru 2 Cl 4 (dppb) 3 [30], and a thiosemicarbazone, generally in the presence of Et 3 N base in toluene/methanol medium. Similarly, Rh I , Pd II and Pt II [26] in ethanol.…”

Vanadium(IV/V) complexes of Triapine and related thiosemicarbazones: Synthesis, solution equilibrium and bioactivity

“…The isotropic EPR parameters of the major isomers (1) [29], which is quite frequent in the case of V(IV)O species and was also observed for other V(IV)O -TSC complexes [24,26]. In the protonation state of VO(IV)L the octahedral "trans", while in the case of complex [V(IV)OL(OH)] the penta-coordinated / octahedral "cis" forms are the most stable species.…”

Intramolecular hydrogen bonds in heterodisubstituted ferrocene diamides

“…Such compounds that have N, O and S donors are good metal-chelating agents [1]. In the last few years the structure of vanadium complexes is of particular interest because of their model character for biological function of vanadium [2]. Series of ligands (scheme) and coresponding complexes with vanadium(V) ions was synthesized in order to investigate the above mentioned properties.…”
