we have recently synthesized [ni (map) ] complex [h-map= 2- (methylamino) pyridine]. 2- (methy1amino)pyridine reacts with meli in thf and generates the lithium salt (li-map). further reaction of nicl with two equivalent of this ligand in thf leads to the formation of a dark red solution. analytical data, molecular weight, and magnetic susceptibility of this complex confirm the formula [ni (map)...

this study reports the synthesis of chitosan anchored schiff base, ([2-oxo-1h-indol-3-ylidene] amino) chitosan and its cu (ii) metal complex. the complex was characterized by elemental analysis, ft-ir spectrum, thermogravimetry analysis .the crystallinity of the compound was analyzed by powder x-ray diffraction technique. the catalytic efficiency of complex was studied in the oxidation of alcoh...

the charge-transfer complexation reaction between iodine and dibenzo- 18-crown- 6 (db18c6) has been studied spectrophotometrically in chloroform solution at different temperatures. the resulting donor-acceptor complex was formulated as (db 18c6…i )i . the spectrophotometric results , as well as the conductivity measurements, indicated that the gradual release of tiiodide ion from its contact io...
