Study of the Influence of a Solvent on the Crystal Structure of an Ethyl-Substituted <i>Bis</i>thiosemicarbazone Ligand

A potentially dianionic symmetric <i>bis</i>thiosemicarbazone ligand H<sub>2</sub>L<sup>Et</sup> has been prepared by a condensation reaction between two equivalents of 4-N-ethyl-3-thiosemicarbazide and one equivalent of 4,4′-methylenebis(acetophenone). The crysta...

Description
Summary:A potentially dianionic symmetric <i>bis</i>thiosemicarbazone ligand H<sub>2</sub>L<sup>Et</sup> has been prepared by a condensation reaction between two equivalents of 4-N-ethyl-3-thiosemicarbazide and one equivalent of 4,4′-methylenebis(acetophenone). The crystal structures obtained from solvents with different donor abilities were studied. The recrystallization of H<sub>2</sub>L<sup>Et</sup> from methanol and dimethylsulfoxide enables the isolation of single crystals suitable for the X-ray diffraction studies of [H<sub>2</sub>L<sup>Et</sup>] <b>1</b> and [H<sub>2</sub>L<sup>Et</sup>]·CH<sub>3</sub>SOCH<sub>3</sub><b>2</b>, respectively. This study shows that the solvent does not affect the macrostructure but influences the microstructure of the ethyl-substituted <i>bis</i>thiosemicarbazone ligand H<sub>2</sub>L<sup>Et</sup>.
