The title compound, C 19 H 12 OS, can be synthesized in good yield (60%) utilizing Vilsmeyer-Haack formylation of 2-(9Hfluoren-9-ylidenemethyl)thiophene. The thiophene ring contains one short C-S bond [1.618 (2) A ˚].
In the title structure, C 16 H 12 N 4 O 3 Á0.5H 2 O, the uncoordinated water molecule lies on a special position of site symmetry 2; O-HÁ Á ÁO and N-HÁ Á ÁO hydrogen bonds link the water and organic molecules into a layer structure.
