here, we report the synthesis of a schiff-base mixed-ligand complex of cadmium(іі) in bulk and nano-scales via the precipitation and sonochemical methods, respectively. the complex formula is [cd(3-bpdh)(3-bpdb)cl2]n (1), where the ligands are 3-bpdh = 2,5-bis(3-pyridyl)-3,4-diaza-2,4-hexadiene and 3-bpdb = 1,4-bis(3-pyridyl)-2,3-diaza-1,3-butadiene. the structure of mixed-ligand complex (1) wa...

Schiff-base ligands are potential anti-cancer, anti-bacterial and anti-viral agents and this activity tends to increase in metal(II) Schiff-base complexes. Some oxindole-Schiff base copper(II) complexes have shown potential antitumor activity towards deferent cells, inducing apoptosis in a process modulated by the ligand. Here, six novel copper(II) complexes with schiff base ligands were isolat...

Reactions of MnX(2) meltsalt (X = Cl and ClO(4)) and a quinquedentate Schiff base ligand together with its coligand azides in MeOH produced the unprecedented assembly of novel octa- and hexadecanuclear manganese clusters containing two and four alternant tetrahedral Mn(III)(3)Mn(II) cores bridged by Schiff base ligands and versatile azides groups. The magnetic measurements on both compounds ind...

Two N4-type Schiff base ligands named N,N'-bis(2-pyridylmethylidene)-1,2-diiminoethane (L1) and N,N'-bis(2-pyridylmethylidene)-1,3-diiminopropane (L2) have been synthesized by the reaction of pyridine-2-carbaldehyde with ethylenediamine and propylenediamine, respectively. The binding abilities of L1 and L2 in dichloromethane towards Cu<...

A new Schiff base ligands (H2L -H2L 3) was synthesized by the condensation reaction of 4-acyl pyrazolones and 2-benzothiazolyl thiosemicarbazide. The ruthenium(II) Schiff base complexes were prepared by the interaction of the ligands with [RuHCl(CO)(EPh3)2(B)] (E=P/As; B=PPh3/AsPh3/py). They were characterized by elemental analysis, IR, UV-vis, 1H, 13C, and 31P NMR spectral data. The interactio...

In the title dinuclear complex, [NiPr(C(19)H(20)N(2)O(4))(NO(3))(3)(CH(3)OH)(2)]·2CH(3)OH, the Ni(II) ion is coordinated by two O atoms and two N atoms of a Schiff base ligand and by two methanol ligands, forming a slightly distorted octa-hedral geometry. The Pr(III) ion is coordinated by six O atoms from three chelating nitrate ligands and four O atoms from a Schiff base ligand, forming a dist...

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 hydrogen bond with the phenoxide group. The ...

An octahedral ruthenium(II) Schiff base complexes of the type [Ru(CO)(Py)L] (L = dianion of the Schiff bases derived from acetoacetanilide with o-phenylenediamine and salicylaldehyde/ohydroxyacetophenone/o-vanillin/2-hydroxy-1-naphthaldehyde) have been synthesized from the reactions of equimolar ratio of [Ru(CO)(PPh3)2(Py)] and Schiff bases in benzene. The formation of the Schiff base ligands a...
