X-ray analysis reveals that both thiosemicarbazone groups of the title comp
ound, [Fe(C8H10N3S)(2)]. H2O, are in the keto tautomeric form and that the
configuration of the azomethine C=N double bond is E. The two cyclopentadie
nyl rings are parallel and nearly eclipsed. The crystal structure is stabil
ized by extensive intra- and intermolecular hydrogen bonding involving the
water molecule and the thiosemicarbazone moieties.
