“…Consequently, we suggest a cationic structure for both the iron(III) and ruthenium(III) complexes (1) and (2) as confirmed by X-ray crystal structure for complex (1). The iron(III) complexes of pyridoxal thiosemicarbazone at temperatures between 50 and 300 K were shown to be either high-spin (S = 5/2) with the neutral thione moiety or low-spin (S = 1/2) when including the thiolate moiety [30], as is also the case for complexes (1) and (2). The components of the g-tensor are greater than those corresponding to the free-electron value (2.0023), indicating that the odd electron occupies an orbital of a largely d xy character [25].…”

Complexes of a diacetylmonoxime Schiff base of S-methyldithiocarbazate (H2damsm) with Fe(III), Ru(III)/Ru(II), and V(IV); catalytic activity and X-ray crystal structure of [Fe(Hdamsm)2]NO3·H2O

The complexes [M(Hdamsm) 2 ]XÁH 2 O (M = Fe, X = NO 3 ; M = Ru, X = Cl), [Ru(Hdamsm)(PPh 3 ) 2 X 0 ] (X 0 = Cl, Br), and [VO(Hdamsm)(acac)] (H 2 damsm = diacetylmonoxime Schiff base of S-methyldithiocarbazate, Hacac = acetylacetone) have been prepared and characterized by spectroscopic techniques. Their redox properties were investigated by cyclic voltammetry. The X-ray crystal structure of [Fe(Hdamsm) 2 ]NO 3 .H 2 O has been determined and shows that the complex has a distorted octahedral geometry in which the Hdamsm behaves as a monoanionic NNS tridentate ligand coordinating via oxime nitrogen, hydrazinic imine nitrogen, and thiolate sulfur. The reactivity of these complexes toward oxidation of alcohols in the presence of t-BuOOH and H 2 O 2 as co-oxidants is reported.

“…[9][10][11] Thiosemicarbazonebased ligands have been used to generate interesting complexes with a range of potential applications, however one area that appeals to us is their use in Fe(III) spincrossover (SCO) systems. [12][13][14][15][16][17] Most examples of thiosemicarbazone-based SCO active complexes use simple thiosemicarbazides and salicylaldehyde (SA) derivatives (e.g. Hthsa, Hth5Clsa and Hth5Brsa, Fig.…”

Three thiosemicarbazone-based ligands and corresponding Fe(III) and Co(III) coordination complexes have been synthesised and fully characterised. Crystallographic analysis of all ligands and complexes revealed interesting hydrogen bonding and π-stacking packing arrangements. Magnetic susceptibility and EPR measurements indicate that the Fe(III) complexes are in the low spin state from 4 -300 K. The complexes exhibit significant solution stability (based on UV/vis and NMR data) and the potential for further functionalisation. Such stability gives solution processability and is ideal for the development of advanced supramolecular materials.

“…As a result, a number of complexes have been prepared and studied with different metals, [1][2][3][4] including the most recently synthesized complexes of V(V) 5 and Mo(VI,V) 6 with these ligands. In contrast to the numerous metal complexes with PLTSC, interest in tridentate ONN pyridoxal isothiosemicarbazone is of a more recent date, so that only a limited number of complexes, namely with COMPLEXES OF VO 2 + AND MoO 2 2+ WITH PYRIDOXAL ISOTHIOSEMICARBAZONE 1065 (Siemens, 1995).…”

Transition metal complexes with thiosemicarbazide-based ligands. Part 57: Synthesis, spectral and structural characterization of dioxovanadium(V) and dioxomolybdenum(VI) complexes with pyridoxal s-methylisothiosemicarbazone

This work is concerned with the synthesis of neutral dioxovanadium(V) and dioxomolybdenum(VI) complexes with tridentate ONN pyridoxal S-methylisothiosemicarbazone (PLITSC) of the respective formulas [VO 2 (PLITSC-H)]·2H 2 O and [MoO 2 (PLITSC-2H)]. Structural X-ray analysis of the vanadium complex showed that it has an almost ideal square-pyramidal structure, while the molybdenum complex is supposed to have a polymeric octahedral structure. In addition to elemental analysis, both complexes were characterized by conductometric and magnetometric measurements, as well as by IR, UV-Vis, 1 H-and 13 C-NMR spectra.
