A new NS pentadentate Schiff base ligand derived from 5-bromothiophene-2-carbaldehyde, ()-1-((5-bromothiophen-2-yl)methylene)-2-(2-(()-((5-bromothiophen-2-yl)-methylene amino) ethyl ethane-1,2-diamine, is prepared. The ligand and its complexes are subjected to extensive physical and theoretical analyses and the results are consistent with their predicted compositions. Dicationic Cu(ii) complexes ([CuNS]X) with a coordination number of 5 are proposed on the basis of the spectral data with NS serving as a pentadentate ligand.

Thiophene-2-carbohydrazide as a novel small-molecule amide tautomer has been synthesized with an acceptable yield under microwave radiation (MW) conditions. The amide imidic thiophene-2-carbohydrazide prototropic tautomerization single proton intramigration was computed using the DFT B3LYP/6-311G(d,p) level of theory. The -isomer amide structure of thiophene-2-carbohydrazide was proved by XRD and is considered to be the kinetically favored isomer.
