Assessment of Water Quality Values in Porur Lake Chennai, Hussain Sagar Hyderabad and Vihar Lake Mumbai, India
Lake water is a source of drinking and domestic use water for rural and urban population of India. The main goal of the present study was to assess drinking water quality of various lakes i.e . PorurExpand
Spectral and magnetic studies on manganese(II), cobalt(II) and nickel(II) complexes with Schiff bases.
Various physico-chemical techniques suggest an octahedral geometry for all the complexes. Expand
Coordination Modes of a Schiff Base Pentadentate Derivative of 4-Aminoantipyrine with Cobalt(II), Nickel(II) and Copper(II) Metal Ions: Synthesis, Spectroscopic and Antimicrobial Studies
The covalency factor (β) and orbital reduction factor (k) suggest the covalent nature of the complexes and the ligand and its complexes have been screened for their antifungal and antibacterial activities against three fungi and two bacteria. Expand
EPR, mass, IR, electronic, and magnetic studies on copper(II) complexes of semicarbazones and thiosemicarbazones.
All the Cu(II) complexes reported here have been characterized by elemental analyses, molar conductance, magnetic moment susceptibility, EI mass, (1)H NMR, IR, EPR, and electronic spectral studies. Expand
Modern spectroscopic and biological approach in the characterization of a novel 14-membered [N4] macrocyclic ligand and its transition metal complexes
A novel tetradentate nitrogen donor [N4] macrocyclic ligand, i.e. 1,3,4,8,9,11-hexaaza-2,5,10,12-tetraoxo-7,14-diphenyl-cyclotetradecane (L), has been synthesized. Mn(II), Co(II), Ni(II) and Cu(II)Expand

A series of 20-memebered macro- cyclic metal(II) complexes have been synthesized by a macro-cyclic ligand and have been found to have distorted octahedral geometry and the binuclear complexes [M2LX2]X2 were found to possess square planar configuration around the central metal ion. Expand
Mn(II), Co(II), Ni(II) and Cu(II) complexes of a tertraaza macrocyclic ligand: Synthesis, characterization and biological screening
Manganese(II), cobalt(II), nickel(II) and copper(II) complexes with 1,5,11,15-tetraaza-21,22-dioxo-tricyclo [19,3,1,I6,10]-5,10,15-20-dicosatetraene (L), as a new macrocyclicligand, have beenExpand
EPR, magnetic and spectral studies of copper(II) and nickel(II) complexes of schiff base macrocyclic ligand derived from thiosemicarbazide and glyoxal.
The complexes from H(2)L(4) show different stoichiometry ratio and with a variable grade of deprotonation in the ligand, depending upon the salt used and working conditions. Expand
EPR, mass, electronic, IR spectroscopic and thermal studies of bimetallic copper(II) complexes with tetradentate ligand, 1,4-diformyl piperazine bis(carbohydrazone).
The synthesis of novel bimetallic Cu(II) complexes with general stoichiometry derived from tetradentate ligand obtained by the condensation of 1,4-diformyl piperazine with carbohydrazide has been discussed and the values of covalency measurements indicate the covalent nature of complexes. Expand
