Five transition metal(II) complexes, [ML(2)Cl(2)] 1 approximately 5, were synthesized from the reaction of MCl(2) x nH(2)O (M = Mn, Co, Ni, Cu, Cd) and the Schiff base ligand 2-[(4-methylphenylimino)methyl]-6-methoxyphenol (C(15)H(15)NO(2), L), obtained by condensation of o-vanillin (2-hydroxy-3-methoxybenzaldehyde) with p-toluidine. They were characterized(More)
The asymmetric unit of the title compound, [Ce(NCS)(3)(C(15)H(15)NO(2))(3)], contains three Schiff base 2-methoxy-6-[(4-methyl-phenyl)iminometh-yl]-phenol (HL) ligands and three independent thio-cyanate ions that coordinate the cerium ion via their N atoms. The protonated imine N atoms are involved in an intra-molecular hydrogen bond with the respective(More)
The Schiff base 2-[(4-methyl-phen-yl)imino-meth-yl]-6-methoxy-phenol (HL) forms a complex with a Zn(2+) atom and two independent thio-cyanate ions, [Zn(NCS)(2)(C(15)H(15)NO(2))(2)], in which two phenolate O atoms the two independent Schiff base ligands are coordinated to thee Zn(2+) atom. The protonated imine N atoms are involved in an intramolecular(More)
The Schiff base 6-meth-oxy-2-[(4-methyl-phen-yl)imino-meth-yl]-phenol (HL) forms a neutral complex with cadmium(II) nitrate, [Cd(NO(3))(2)(C(15)H(15)NO(2))(2)], in which the four O atoms of the two independent ligands are coordinated to the metal center and the protonated imine N atoms are involved in a hydrogen bond with the phenoxide group.(More)
A new dinuclear complex, [Ni(2)(H(2)O)L(4)].5H(2)O, consisting of chelating bidentate and bridging tridentate coordinated 2-[(4-methylphenylimino)methyl]-6-methoxyphenol (HL) Schiff base ligands and water molecules has been synthesized using a traditional method. The structure of this complex was characterized by FTIR and UV/Vis spectroscopy and(More)
The structure of the title compound, [Cd(3)Cl(6)(C(15)H(15)NO(2))(2)(CH(4)O)(2)](n), is based on a layered zigzag polymeric chain along the c axis. The Cd(II) ions are linked by double chlorine bridges alternating between one CdCl(4)(CH(3)OH)(2) and two CdCl(4)(C(15)H(15)NO(2)) octa-hedral coordination units. Additional intrachain N-H⋯O and O-H⋯Cl(More)
