Sj. Swamy et Ad. Reddy, Synthesis of iron(III), cobalt(II), nickel(II), copper(II) and zinc(II) completes with new quadridentate N, O- donor ligands, J INDIAN CH, 77(7), 2000, pp. 336-338
The reaction between anthranilic acid and oxalyl chloride/malonyl chloride
results in new quadridentate ligands, bis(2-carboxyphenyl)oxamide [CPOA]/bi
s(2-carboxyphenyl)malonamide [CPMA]. These ligands form 1 : 1 complexes of
general formula, [Fe(L)(H2O)(2)]Cl, [M(L)] and [Zn(L)](.)2H(2)O, where L =
CPOA or CPMA, M = Co-II, Ni-II or Cu-II.
