The title compound, C(15)H(12)I(2)N(2)O(3), was synthesized by the condensation of equimolar amounts of 3,5-diiodo-salicylaldehyde and 2-methoxy-benzohydrazide in a methanol solution. There are two independent mol-ecules, A and B, in the asymmetric unit. The dihedral angle between the two benzene rings is 30.2 (2)° for mol-ecule A and 21.7 (2)° for mol-ecule B. There are intra-molecular O-H⋯N a...

The title compound, [Cu(2)(NCS)(2)(C(13)H(17)Cl(2)N(2)O)(2)], was obtained by the reaction of 3,5-dichloro-salicylaldehyde, N,N-diethyl-ethane-1,2-diamine, sodium thio-cyanate, and copper(II) acetate in an ethanol solution. It crystallizes as a centrosymmetric dimer with a very long Cu⋯S axial bond [2.972 (3) Å]. The Cu atom is five-coordinated by the three donor atoms of the Schiff base ligand...

Amino acid ionic liquid-supported Schiff bases, derivatives of salicylaldehyde and various amino acids (L-threonine, L-valine, L-leucine, L-isoleucine and L-histidine) have been investigated by means of various spectroscopic techniques (NMR, UV-Vis, IR, MS) and deuterium isotope effects on ¹³C-NMR chemical shifts. The results have shown that in all studied amino acid ionic liquid-supported Schi...

An improved method of sample preparation was used in a microplate assay to evaluate the bactericidal activity levels of 96 essential oils and 23 oil compounds against Campylobacter jejuni, Escherichia coli O157:H7, Listeria monocytogenes, and Salmonella enterica obtained from food and clinical sources. Bactericidal activity (BA50) was defined as the percentage of the sample in the assay mixture...
