Chemistry of mixed-ligand methoxy bonded oxidovanadium(V) complexes with a family of hydrazone ligands containing VO3+ core and their substituent controlled methoxy-bridged dimeric forms

Chemistry of molecular and supramolecular structures of vanadium(IV) and dioxygen-bridged V(V) complexes incorporating tridentate hydrazone ligands

“…The V-N1 bond distance of 2.110(2) Å is marginally shorter than the V-N2 bond distance of 2.1256(18) Å. The intramolecular VÁ Á ÁV bond distance is 3.1463(7) Å, which falls within the range of known VÁ Á ÁV distances in doubly-bridged vanadium polynuclear systems [25,26]. To a first approximation, the molecular structure of the complex in [VO(DKN)l 2 -O)] 2 Á½H 2 O (2) resembles that just described, Fig.…”

A journey into the electrochemistry of vanadium compounds

“…Another series of VO 3+ complexes prepared with the same set of ligands [170] had the formula VOL(OMe), with L = achybz, ac Me hybz and ac Cl hybz; instead, ac OMe hybzH 2 gave only the dimeric V 2 O 2 (ac OMe hybz) 2 (-OMe) 2 (from which the authors were, nevertheless, able to obtain the mononuclear complex). Similar dinuclear compounds were prepared independently also with achybz and ac Me hybz ligands (Table 6, entries 19-21).…”

(Acetylacetonato-κ2O,O′)aqua[2-(2-nitrophenoxy)-N′-(2-oxidobenzylidene-κO)acetohydrazidato-κ2O,N′]manganese(III)

“…(2009). E65, m986 [doi:10.1107 The design and construction of hydrazone complexes are of great interest due to their various structures and their biological activities and chemical versatility (Liu & Gao, 1998;Iskander et al, 2001;Cariati et al, 2002;Sreekanth et al, 2004;Bai et al, 2006;Mondal et al, 2008). Relatively speaking, only a few crystal structures of phenoxyacetylhydrazone complexes have been studied (Chen & Liu, 2004;Sun et al, 2005;Chen & Liu, 2006).…”
