This article describes the synthesis of isonitrosomethyl-p-tolyl ketone [HL] as the starting compound and then we prepared the new oxime ligand from the reactions of the amine materials with 1,2-diaminobenzene [H2L1]. (1E, 2E, 1'E, 2'E)-3,3'-bis [(4-tolyl ketone)-(1,2 phenylene diimine)]. Acetaldehyde dioxime ligand was used to synthesize the metal complexes. The complexes were elucidated by FT-IR, elemental analysis, magnetic moment measurements, molar conductivity, mass spectra, and TGA studies. The free ligand was also described with its13C and1H-NMR spectra. For complexes using spectroscopic and stoichiometric data of the complexes showed that metal:ligand ratio of mononuclear copper(II) complex was found to be 1:1 while this ratio was 2:1 in homo-and heterodinuclear copper(II) complex and 3:2 in the trinuclear copper(II) complex. All these data show us that the proposed structure is consistent with the obtained data. © 2018, Turkish Chemical Society. All rights reserved.

Two new heteronuclear Nickel(II)/Sodium(I) complexes of a side-off compartmental Schiff base ligand were synthesized and characterized by spectroscopic methods. Crystal structures of both of the complexes were also obtained. The Schiff base ligand was synthesized from the condensation of meso-1,2-diphenyl-1,2-ethylenediamine with 2-hydroxy-3-methoxybenzaldehyde. In both of the complexes the Ni(II) ion is coordinated to the inner N 2 O 2 coordination sphere with square-planar geometry and the Na(I) ion is coordinated to the outer O 2 O 2 ′ coordination sphere. In Complex ( 1 ) with general formula [Ni(L)Na(CH 3 OH)(ClO 4 )] the sodium ion is seven coordinated while in ( 2 ) with general formula [{Ni(L)Na(OH 2 )} 2 (μ-Ni(CN) 4 )] the sodium ion is six coordinated. Intermolecular interactions in two studied complexes were analyzed using 3D Hirshfeld surfaces and corresponding 2D fingerprint plots. This analysis showed that the H … H and C … H/H … C contacts for both structures (altogether 67.5% of total Hirshfeld surface area for ( 1 ) and 77.6% for ( 2 )) and the O … H/H … O (24.2%) for ( 1 ) and the N … H/H … N (8.1%) contacts for ( 2 ) were the characteristic intermolecular contacts in the related crystal structures.

A new hetero trinuclear manganese(III)-iron(II) complex, [Mn(salen)(H 2 O)] 2 [Fe(CN) 6 ], in which salen is the dianionic form of N,N’-bis(5-methylsalicylidene)-1,2-diaminoethane, has been prepared and characterized by elemental analyses, IR, and single crystal X-ray crystallographic determination. The crystal of the complex is monoclinic: space group P 2 1 / c , a = 10.768(2), b = 14.248(3), c = 15.222(3) A, β = 95.394(2)o, V = 2325.0(8) A 3 , Z = 2, R 1 = 0.0754, wR 2 = 0.2366. The bis-Schiff base ligand coordinates to the Mn atom through phenolate O and imine N atoms. Each Mn atom in the complex is in octahedral coordination, with the equatorial donor atoms come from the Schiff base ligand, and with the axial donor atoms come from a water O atom and a cyanide N atom. The effects of the complex on the antimicrobial activity against Staphylococcus aureus , Escherichia coli , and Candida albicans were studied.
