No full textThe formation of vanadyl(IV) complexes with acetates were studied by potentiometric titrn. methods; the stepwise formation consts. of mononuclear complexes, [VO(CH3COO)]+ and [VO(CH3COO)2], were calcd. to be 72.2 and 12.6 M-1, resp., in 1 M aq. perchlorate at 25 °C. A comparison was made with the literature values for the corresponding neptunyl(IV) complexes
Synthesis, characterization and spectroscopic investigations of tin(IV) and organotin(IV) derivatives of 4-aroyl-5-pyrazolones. Crystal structure of trans-dimethylbis[1-phenyl-3-methyl-4-(4bromobenzoyl)-pyrazolon-5-ato]tin(IV).
No full textCopper and calcium complexes with the anionic O2-donor 4-tert-butylacetyl-3-methyl-1-phenylpyrazol-5-onato (Q-). Influence of hydrogen-bond interactions on lattice architecture in the crystal structures of [CuQ2(H2O)] and [CaQ2(EtOH)2]
No full textVanadyl(IV) - Monocarboxylate Complexes in Aqueous Solution.
No full textThe complex formation of vanadyl(IV) with monochloroacetate, β-chloropropionate and glycolate ions was studied by potentiometric [H+] measurements in 1 M NaClO4 soln. at 25 °C. The VO2+ ion forms mononuclear successive complexes with a coordination no. > 2. The relationship between the stability of the vanadyl complexes and the ligand basicity is discussed
