NEW COPPER(II) CHELATES WITH SHIFF BASES — CONDENSATION PRODUCTS OF SALICYLIC ALDEHYDE AND AMINONAPHTHALEN DERIVATIVES

Abstract

The copper (II) complexes (I—III) with Schiff bases — condensation products of salicylic aldehyde with 1-aminonaphthalen (HL1), 1,8-diaminonaphthalen (H3L2), 1-amino-8-naphthalensulfonic acid (H2L3): [Cu(HL1)2(H2O)2] (I), [Cu(H2L2)2] (II), [Cu(HL3)2](III) — were synthesized. I—III were investigated by elementary analysis, X-ray powder diffraction, thermogravimetry, magnetic susceptibility and electric conductivity measurements, IR and diffuse reflectance spectroscopy. The way of coordination and the geometry of synthesized complexes were determinated.
