Synthesis and Crystal Structure of Non-symmetric Tetradentate Complexes of Ni(II), Cu(II), Co(II), and Zn(II)
摘要:
The non-symmetrical tetradentate Schiff-base H(2)L have been obtained using the half-unit N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine (HL(1)) with 2-hydroxyl-1-naphthaldehyde. ML complexes(M= Ni(1), Cu(2), Co(3) and Zn(4)) were prepared and characterized by atomic absorption, IR, UV, (1)H NMR spectroscopy, and a single crystal X-ray structure. Crystal data for (1) are triclinic space group P-1, a = 7.9784 (3) angstrom, b = 10.2417 (4) angstrom, c = 13.4090 (5) angstrom, alpha = 103.8480 (10)degrees, beta = 97.0540 (10)degrees, gamma = 92.2400 (10)degrees and z = 2. Crystal data for (2): Triclinic space group P-1, a = 7.9991 (6) angstrom, b = 10.0520 (7) angstrom, c = 13.6974 (10) angstrom, alpha = 103.6500 (10)degrees, beta = 95.9650 (10)degrees, gamma = 90.3160 (10)degrees and z = 2. The Ni and Cu atoms have slightly distorted square-planar coordination geometry.
