Abstract

Abstract: Modified α and β bis(salicylaldoxime)copper(Ⅱ) have been obtained by recrystallization from ethyl acetate(CCDC Nos. 212157 & 212158). The X-ray analysis reveals that the two modificated forms have the same structure with different geometric parameters. The α form crystallizes in the P2(1)/c space group and the β form in the P1 space group. Both the crystal structures consist of centrosymmetric monomeric molecules of Cu(OC₆H₄CNOH)₂. The IR spectra are in agreement with the structural data.

Key words: Copper(Ⅱ) complexes, Salicylaldoxime, X-ray analysis, Crystal structures
