Abstract A new vic‐dioxime ligand, [5,6;11,12‐di(cyclohexyl)2,3‐bis(hydroxyimino)‐8,9‐diimino‐1,4‐diazacyclododecanenickel(II)]chloride, [NiDHDD]Cl2 (2), has been synthesized by the template condensation reaction of [N,N′‐bis‐(2‐aminocyclohexyl)‐ethanedialdiminenickel(II)]chloride, [NiBAED]Cl2 (1) with anti‐dichloroglyoxime in methanol solution at −10 °C. A homotrinuclear complex of [NiDHDD]Cl2 (2), is formed with Ni(II) chloride and a heterotrinuclear complex of this ligand with Cu(II) chloride has been synthesized. The complexes [M(NiDHDD)2]Cl4 have been characterized on the basis of elemental analyses, magnetic susceptibility measurements, conductivity measurements, IR and electronic spectral studies. The trinuclear Ni(II) and Cu(II) complexes of the vic‐dioxime ligand [NiDHDD]Cl2 (2), have a M:ligand ratio of 1:2 and the ligand coordinates only through the N,N atoms, as do most vicinal dioximes. The molar conductivities in DMF solution indicate the electrolytic nature for the complexes.

Abstract The template condensation reaction of 2,6‐diacetylpyridine and 2,6‐diaminopyridine forms a novel series of 20‐membered N8 macrocyclic complexes. The proposed stoichiometry and the nature of the macrocyclic complexes have been confirmed on the basis of elemental analyses and conductivity data, respectively. The bonding in these complexes has been envisaged from the findings of IR and 1H NMR spectral studies, while the overall geometry has been deduced from the results obtained from UV‐Visible, EPR spectral, and magnetic measurements.

Abstract Two new Schiff bases have been synthesized by the reaction of p‐aminoazobenzene with salicylaldehyde (L1H) and the oxidative polycondensation product of L1H (L2H2). The complexes of cobalt(II), copper(II), and nickel(II) with L1H and L2H2 have been prepared. The ligands and their complexes have been characterized by elemental analyses, IR spectra, electronic absorption spectra, mass spectra, 1H and 13C NMR spectra, and magnetic susceptibility measurements. The thermal properties of all complexes have been studied by TG and DTA. The analytical data show that the metal to ligand ratio in the L1H complexes is 1:2, but in the L2H2 complexes it is 1:1.

Abstract Synthesis of 2‐(thiomethyl‐2′‐benzimidazolyl)benzimidazole (L) and its metal complexes of the formulae ML2(ClO4)2 · xH2O (M = Co, x = 3; M = Ni, Zn, or Cd, x = 2; M = Cu, x = 1) and MLBr2 (M = Co, Ni, Cu, Zn, or Cd) are described. They have been characterized by measuring physical properties, IR, NMR, and electronic spectral studies. The electronic spectral and magnetic moment data suggest an octahedral geometry for the cobalt(II) and nickel(II) perchlorate complexes, a tetrahedral geometry for the cobalt(II) and nickel(II) bromo complexes and a pseudo tetrahedral geometry for the copper(II) perchlorate and copper(II) bromide complexes. Based on elemental analyses, conductivity measurements and IR and NMR spectral studies, a six‐coordinate geometry for cadmium perchlorate complex and various four‐coordinate geometries for zinc perchlorate and bromo complexes of cadmium and zinc have been proposed.

Abstract Four new binuclear iron(II) complexes with a tetracarboxylato‐bridge have been synthesized and characterized, namely [Fe2(PMTA)L4], where L denotes 4,7‐diphenyl‐1,10‐phenanthroline (Ph2‐phen); 2,9‐dimethyl‐1,10‐phenanthroline (Me2phen); diaminoethane (en); 1,3‐diaminopropane (pn) and PMTA represents the tetraanion of pyromellitic acid. Based on elemental analyses, magnetic moments at room‐temperature and molar conductivity measurements, spectroscopic (electronic and IR spectra) studies, it is proposed that these complexes have PMTA‐bridged structures and consist of two iron(II) ions in a distorted octahedral environment. The variable‐temperature magnetic susceptibilities (4–300 K) of the complexes [Fe2(PMTA)(Ph2phen)4] (1) and [Fe2(PMTA)(Me2phen)4] (2) were measured and studied in detail. The magnetic analysis was carried out by means of a least‐square method to the observed data with the susceptibility equation derived from the spin Hamiltonian operator, Ĥ = −2JŜ 1 Ŝ 2, giving the exchange integrals J = −0.96 cm−1 for (1) and J = −0.85 cm−1 for (2). The results indicate that there is a very weak antiferromagnetic spin‐exchange interaction between the two Fe(II) ions within each molecule.

Abstract Complexes of transition metals with salicylaldehyde (salH) or 5‐bromo‐salicylaldehyde (Br‐salH) in 1:2 molar ratio, have the compositions [M(H2O)2(sal)2] · H2O (1) or [M(H2O)2(Br‐sal)2] · H2O (2), respectively. The Schiff base derived from ethylenediamine and acetophenone in 1:1 molar ratio in alcoholic solution yields bis(acetophenone)ethylenediamine (acphen). Further reaction of (1) or (2) with acphen in alcohol yielded mixed‐ligand complexes of the type [M(sal)2acphen] or [M(Br‐sal)2 acphen], respectively. All of these complexes are soluble in ethanol and methanol. They were characterized on the basis of elemental analyses, magnetic measurements, infrared spectra, electronic spectra, and thermogravimetric analyses. All of these complexes have been screened for their antimicrobial activity against bacterial strands using the agar diffusion method.

Abstract Three novel N,O‐bidentate Schiff bases H2L1, H2L2, and H2L3 have been prepared and investigated. H2L1 underwent self‐assembly with silver(I) nitrate forming the supramolecular complex [Ag2(H2L1)3] n (NO3)2n , whereas H2L2 and H2L3 do not form supramolecular complexes due to the chain length of the bidentate Schiff bases, which prevent Ag–N interactions. The results indicate the effect of the chain length of diamine, the presence of active phenol group, and the arrangement of silver(I) interactions on the formation of three‐dimensional (3D) supramolecular complex.
