Abstract
- Oxovanadium(IV) and dioxouranium(VI) complexes of 1-(2-pyridylazo)-2-naphthol (PAN) and 4-(2-pyridylazo) resorcinol (PAR) have been prepared and characterised by elemental analyses, various physico-chemical methods and magnetic measurements. The I. R. observations suggest that PAN is coordinated through oxygen and (pyridine) nitrogen, whereas PAR is coordinated through (pyridine) nitrogen and the ortho-hydroxyl group. The spectral-studies suggest that oxovanadium(IV) complexes have the coordination number five and dioxouranium(Vl) complexes have the coordination number six for the cations.
