Spectrophotometric Study of Nitrogen Base Adducts of Nickel(II)-4-methyl-8–quinolinate

Spectrophotometric Study of Nitrogen Base Adducts of Nickel(II)-4-methyl-8–quinolinate

Adduct formation constants have been determined by spectrophotometric study of a few typical bases with nickel(II) chelate of 4-methyl-8-quinolinol in chloroform. Bathochromic and hypsochromic shifts were observed in the visible range due to the adduct formation. Monobasic bases like pyridine, methy...
