Thiosemicarbazones and Their Transition Metal Complexes

Ligand Field Parameters of Some Transition Metal Ion Complexes of Some Substituted Hydrazones and their Antibacterial Activity

Potentiometric studies have been carried out on transition metal complexes of Mn+2, Co+2, Ni+2, Cu+2, Zn+2 with hydrazones synthesized from 4-amino benzoic acid hydrazide and 2-hydroxy-1acetonephthone/2-hydroxy-1-naphthaldehyde. The dissociation constants of ligand and formation constants of its metal complexes have been determined by Calvin-Bjerrum pH titration technique, as adopted by Irving ...

Synthesis and Characterization of Some Transition Metal Complexes of Arylidene Salicyloyl and Benzoyl Hydrazones

Complexes of arylidene salicyloyland benzoyl-hydrazones with the 3d metal ions, C r(III), M n(II), F e (III), C o (II), N i(II) and C u (II), have been prepared using 2:1 ligand to metal ion ratio. Characterization of the isolated solids was accomplished by IR and electronic spectra, elemental analysis, and molar conductivity measurements. It is concluded that the two Schiff bases function as n...

STUDIES OF TRANSITION METAL COMPLEXES WITH 2N-QUINOLYL- AND 2N-ISOQUINOLYL- 1,1,3,3-TETRAMETHY LGUANIDINES

Ligands derived from 8-quinoline, 6-quinoline, 1 -isoquinoline, and 5-isoquinoline were synthesized. These compounds have been used as ligands for complexation of transition metals, such as copper(II) and nickel(II). According to the spectrosocopic data, copper(II) cation forms (I: 1) and (I:2) complexes with 2-(8-quinoly1)-l,l,3,3- tetramethylguanidine and 2- (I '-isoquinoly1)- 1,1,3,3-tetr...

Studies of Transition Metal Complexes and Their Antibacterial Activities

Tetraaza Macrocyclic complexes of transition metals of Ni (II), Cu(II), Cr(III), Fe(III), Mn(II) were synthesized in methanolic media by template method. The complexes were characterized by elemental analysis, UVVis, Infrared spectroscopy. In vitro antibacterial activity of macrocyclic complexes against five bacteria i.e. Streptococcus mutans, Escherichia coli, Staphylococcus aureus, Streptococ...
