COPPER(II) COMPLEXES OF SCHIFF-BASES DERIVED OF 2-HYDROXY-3-NAPHTHALDEHYDE - THE CRYSTAL AND MOLECULAR-STRUCTURES OF BIS-((PHENYL) [(2-OXO-3H-NAPHTH-3-YLIDENE)METHYL]AMINATO) COPPER(II) AND BIS-((BENZENE-4-TRIFLUOROMETHYL) [(2-OXO-3H-NAPHTH-3-YLIDENE)-METHYL]AMINATO)COPPER(II)

The Schiff base ligands, 3-[(Phenyl)-2-hydroxy-3H-Naphth-3-ylidene)methyl]aldamine (1) and 3-[(benzene-4-trifluoromethyl)-2-hydroxy-3H-naphth-3-ylidene)methyl]aldamine (2), and their corresponding Cu(II) complexes (I and II were synthesized. The crystal and molecular structures of I and II were determined. Compound I crystallizes in the triclinic crystal system a = 10.804(5), b = 12.589(5), and c = 10.369(3) (angstrom), alpha = 107.72(3), beta = 95.75(3), and gamma = 76.32(4)(degrees), in the space group P1BAR with Z = 2. Compound II crystallizes in the triclinic crystal system a = 10.718(2), b = 13.861(4), and c = 10.110(9)(angstrom), alpha = 95.99(2), beta = 90.16(2), and gamma = 93.90(2)(degrees), in the space group P1BAR with Z = 2. The geometry around the metal atom in both complexes I and II is square planar.
