Abstract
The 1-phenylglyoxal bis {N(4)-methyl- and {N(4)-ethylthiosemicarbazones}, H (2)Pg4M and H(2)Pg4E, have been prepared, studied spectroscopically (H-1 NM R, ultraviolet and infrared) and their crystal structures solved, Intramole cular hydrogen bonding connects the two thiosemicarbazone moieties in both H(2)Pg4M and H(2)Pg4E such that they are on the same side of the carbon-car bon backbone, and N(4)H hydrogen bonds to the azomethine nitrogen for each moiety.
