The molecular structures of two salicylaldehyde thiosemicarbazone derivatives, namely salicylaldehyde 4-phenylthiosemicarbazone, C(14)H(13)N(3)OS, (I), and 4-methoxysalicylaldehyde 4-phenylthiosemicarbazone, C(15)H(15)N(3)O(2)S, (II), both of potential pharmacological interest, are found in the keto (thione) tautomeric form. The first compound represents a second triclinic polymorph of composition beta-C(14)H(13)N(3)OS. Although both polymorphs crystallize in the same space group (P1), the…

TLDR
The title compound, [(Z)-4-allyl-2-(2-hydroxybenzylidene)thiosemicarbazone-κS], crystallized as a rotational twin in the monoclinic crystal system with two formula unit (Z' = 2) in the asymmetric unit, one of which contains an allyl substituent disordered over two positions.
[3-({(E)-2-[(4-Fluorophenyl)carbamothioyl]hydrazinylidene}methyl)-4-hydroxybenzyl]methyltriphenylphosphonium chloride
TLDR
The cation in the title salt, C33H28FN3OPS+·Cl−, is highly twisted with the phosphonium group occupying a position almost normal to the central hydroxylbenzene ring, allowing for the formation of an intramolecular N—H⋯N hydrogen bond.
