the in-situ method of synthesis has been used to isolate oxovanadium(iv) complexes with ligands derived by reaction of benzil with amino acids such as glycine, alanine, serine, cysteine and valine, where template effect of vo +2 cation appears to play an important role. the complexes are characterised by elemental analysis, magnetic moment measurements and spectral (infrared, electronic and ele...
A series of new complexes of a general motif [R2E(μ-N,S)2TM-L] (E: metalloid group 14 element; TM: group 10 metal; R: Cl, Ph, pyS, OH, (N,N,O)-chelating ligands; N,S: 1-methylimidazole-2-thiolate (methimazolyl, mt(-)), pyridine-2-thiolate (pyS(-)); L: PPh3, PCy3, pyS) was synthesised and characterised by single-crystal X-ray diffraction, multi-nuclear NMR spectroscopy ((1)H, (13)C, (31)P, (119)...
The equilibrium constant of adduct formation between some triorganotin chloride of the type R3SnCl (R=C6H5, p-CH3C6H4, n-CH3)CH2)3, C6H5-CH2 and Lewis bases Cl¯, Br¯, and I¯, were measured in 50% v/v ethanol-water solvent spectrophotometrically. The average equilibrium co...
the melt-phase synthesis of dioctyltin (iv) and triphenyltin (iv) benzoates were carried outusing stoichiometric amounts of benzoic acids and the corresponding organotin (iv) compounds.the reagents were ground together in a mortar and fed into a boiling glass tube. a cannula tubewas inserted into the boiling tube to discharge accumulated gaseous products. a syringe ensureda continuous flow of d...
Reaction of R2SnCl2 (R = Me, nBu, Ph) and the potassium salts of salenN3H3 (N,N0-bis(salicylidene)diethylenetriamine) and saleanN3H5 (N,N0-bis(o-hydroxybenzyl)diethylenetriamine) provided diorganotin(IV) complexes of the composition [Me2Sn(salenN3H)] solvate (solvate = 2.5H2O, MeOH or DMSO), [nBu2Sn(salenN3H)] H2O, [Ph2Sn(salenN3H)] 2EtOH and [Me2Sn(saleanN3H3)] 2.5H2O. In all compounds the tin...
