Rn. Patel et Kb. Pandeya, SYNTHESIS AND X-BAND EPR-SPECTRA OF BINARY AND TERNARY COMPLEXES OF COPPER(II) WITH SALICYLIDENEANTHRANILIC ACID AND IMIDAZOLES, Synthesis and reactivity in inorganic and metal-organic chemistry, 27(8), 1997, pp. 1149-1157
The synthesis and EPR spectra of some binary and ternary complexes of
copper(II) with a terdentate ligand, salicylideneanthranilic acid (H(2
)SAA) and some monodentate imidazoles viz. imidazole (im) and 2-ethyli
midazole (e-im), are described. The binary complex with copper(II) and
salicylideneanthranilic acid shows a subnormal magnetic moment and EP
R spectra for spin-spin interaction. The zero-field splitting paramete
r D has been evaluated as 190 G and the copper-copper distance as 5.22
7 Angstrom. The ternary complexes show magnetic moments and EPR spectr
a which suggest a distorted tetrahedral geometry around copper(II).
