摘要：

1-phenyl-1,2-propanedione bis{N(4)-methyl- and {N(4)-ethylthiosemicarbazone}, H(2)Pm4M and H(2)Pm4E, respectively, have been prepared, studied spectroscopically (H-1 NMR, ultraviolet and infrared) and their crystal structures solved. Intermoiety hydrogen bonding does not occur in H(2)Pm4M and H(2)Pm4E, in contrast to the analogous bis{N(4)-thiosemicarbazones} prepared from 1-phenylglyoxal, The two thiosemicarbazone moieties are on the opposite side of the carbon-carbon backbone, but the N(4)Hs intramolecularly hydrogen bond to the imine nitrogen for each moiety.
