New zinc(II) and cadmium(II) complexes of the 2,2’-diamino-4,4’-bithiazole (DABTZ) ligand, [M(DABTZ)2(CH3COO)](ClO4), have been synthesized and characterized by elemental analysis, IR, 1H NMR and 13C NMR spectroscopy. The structural characterization of the Cd(DABTZ)2(CH3COO)](ClO4) · 2H2O complex shows the complex to be a monomer and the Cd atom to be coordinated by four nitrogen atoms of the “DABTZ” ligands and two oxygen atoms of the acetate anion. There is an edge-to-edge π-π stacking interaction between the parallel aromatic rings.

New Compounds

Acylhydrazinecarbothioamides (2a,b) were synthesized by addition of 2-(5H-dibenzo[a,d][7]annulen-5-yl)acetohydrazide to different isothiocyanates. The new 1,2,4-triazol-3-thioles (3a,b) were synthesized by cyclization of new 2- acylhydrazinecarbothioamides (3a,b) in basic media. Alkylation of 1,2,4-triazole-3-thiols (3a-c) with ethyl bromide gave only S-substituted derivatives (4a-c). The structures of the synthesized compounds have been established on spectral data (IR, 1H-NMR and 13C-NMR spectroscopy) and elemental analysis. The cytotoxic effect of new compounds was evaluated using two alternative models on plant and invertebrate organisms.

Ullmann Coupling

New 4-substituted 9,10-anthraquinones (6 compouds) with amino derivations fragments were synthesized through the substitution of the bromaminic acid by amines using the Ullmann coupling reaction. The structures of the synthesized compounds were determined using LC-MS, 1H NMR, 13C NMR spectroscopy, and elemental analysis data.

Anew bidentate ligand butyl-(1-methyl-3-phenyl-propyl)-dithiocarbamate (bm?pdtc) was prepared, as the sodium salt. In the reaction of hexaaminecobalt(III) chloride with Nabm?pdtc, the corresponding tris[butyl-(1-methyl-3-phenyl-propyl)-dithiocarbamato]cobalt(III) [Co(bm?pdtc)3]?complex was prepared. The complex was characterized by elemental analysis, infrared, electronic absorption, 1H and 13C-NMR spectroscopy.
