Synthesis, Spectral, Thermal and Antimicrobial Studies of Ni (II) Complexes with Oxygen Donor Ligands: Part-1
Anshu Khandelwal | Mithlesh Agrawal [4]
Abstract: The mixed ligand complexes of Ni (II) derived from the condensation of 5-nitrosalicylaldehyde (HL1) as primary ligand and secondary ligands (HL2) like salicylaldehyde, substituted salicylaldehyde or 2-hydroxyaryl ketones were synthesized in 111 molar ratios and characterized by elemental analysis, TGA, magnetic measurements, conductometery, IR and UV-visible spectroscopy and amicrobial study. These O-donor ligands are act as bidentate monobasic and coordinating through deprotonated phenolic oxygen and carbonyl oxygen atoms. The presence of the two coordinated water molecules in these complexes was indicated by IR spectra and TGA of the complexes The studies revealed octahedral geometry of synthesized complexes.
