Bv. Agarwala et al., PHYSICOCHEMICAL STUDIES OF (O-VANILLIN THIOSEMICARBAZONATO)-NICKEL(II) CHELATE, Transition metal chemistry, 19(1), 1994, pp. 25-27
Five- and six-membered rings result from the chelation of nickel(II) b
y the dibasic tridentate Schiff base ligand, o-vanillin thiosemicarbaz
one(o-VTSC), a new chelate prepared and characterized. The structural
results are discussed in the light of spectroscopic and other data.
