Synthesis and characterization of non-symmetric tetradentate complexes of Zn(II), Co(II), and Cu(II)

摘要

The non-symmetrical tetradentate Schiff-base H_2L wasobtained using the half-unit N-(1-hydroxy-2-acetophenone)-1-amino-2-phenyleneimine (HL) with 2-hydroxyl-1-naphthaldehyde. ZnL, CoL, andCuL complexes were prepared and characterized by ^1H-NMR, IR,electronic, and atomic absorption spectra. The single crystal X-raystructure of CuL was determined. Crystal data for CuL are triclinicspace group P-1, a = 8.3933 (17) ?, b = 11.197 (2) ?, c = 13.381 (3)?, lpha = 95.29 (3)°, eta = 94.37 (3)°, gamma = 95.82 (3)°, andz = 2.
