چکیده | ||
Metal complexes, ML (M=Ni, Cu, Co and Zn) of unsymmetrical tetradentate schiff base have been synthesized by the template reaction of the half-units N-(1-hydroxy-2-acetonaphthone)-1-amino-2-phenyleneimine)(HL1) with 2-Pyrroleca-rbaldehyde. The complexes have been characterized by elemental analysis, IR, 1H NMR and UV spectroscopy. The crystal structure of the Ni(II) complex has been determined by X-ray and exhibits distorted square-planar conformation. Crystals of NiL are orthorhombic, space group P212121, with a = 7.1635(6), b = 11.6815(10), c = 20.7217(17) ? and Z = 4. The Ni-O and Ni-N bonds have very similar lengths and form a regular square-planar structure. | ||
