Magneto, spectral and thermal studies on Co~(2+), Ni~(2+), Cu~(2+), Zn~(2+), Cd~(2+), UO_2~(2+) and VO~(2+) chelates of o-(N-#alpha#-pyridimino) phenol and o-(N-#alpha#-pyrrolidimino) phenol

摘要

Solid chelates of Co~(2+), Ni~(2+), Cu~(2+), Zn~(2+), Cd~(2+), UO_2~(2+) and VO~(2+) with o-(N-#alpha#-pyridimino) phenol (H_2PP) and o-(N-#alpha#-pyrrolidimino) phenol (H_2PP') have been synthesised and characterised by different physico-chemical techniques. Elemental analysis, magnetic, conductance, spectroscopic (electronic IR, and ~1H MNR) and thermal studies conducted on solid chelates suggest in octahedral stereochemistry for Co~(2+), Ni~(2+), UO_2~(2+) and VO~(2+) chelates. Various bonding parameters were also evaluated.
