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 [P—C—C—C tosrsion angle = −100.9 (3)°], and with the hydrazone substituent twisted out of the plane [C—C—C—N torsion angle = 13.1 (4)°]. The fluorobenzene ring is twisted out of the plane of the adjacent thiourea residue, forming a dihedral angle of 51.69 (10)°. The configuration about the C=N bond [1.281 (4) Å] is E, the O—H and N—H hydrogen atoms are syn, and in the thiourea residue, the N—H hydrogen atoms are anti, allowing for the formation of an intramolecular N—H⋯N hydrogen bond. In the crystal, dimeric aggregates mediated by N—H⋯S bonds are formed, which are linked to the Cl− anions by O—H⋯Cl hydrogen bonds. The four-component aggregates are linked into a three-dimensional structure by C—H⋯Cl interactions.

(3-Formyl-4-hydroxy-phenyl)methyl-triphenyl-phosphonium chloride (0.382 g, 1 mmol) was dissolved in ethanol (30 ml) and added to an ethanolic solution (20 ml) of 4-fluorophenyl-3-thiosemicarbazide (0.18 5 g, 1 mmol). The reaction mixture was refluxed for 4 h and the title compound separated as a yellow powder upon cooling. Recrystallization from ethanol afforded yellow crystals.
Carbon-bound H-atoms were placed in calculated positions [C—H 0.95 to 0.99 Å, Uiso(H) = 1.2Ueq(C)] and were included in the
in the riding model approximation. The O—H and N—H H-atoms were located in a difference map and refined with distance restraints of 0.84±0.01 and 0.88±0.01 Å, respectively, and with unrestrained Uiso(H).As part of efforts in improving the water solubility and biological properties of thiosemicarbazones (Kalinowski et al., 2009; Beraldo & Gambino, 2004), we report herein a new thiosemicarbazone molecule characterized as its Cl- salt, (I), containing a cationic triphenylphosphonium moiety, which is known to exhibit biological properties (Shahabadi et al., 2010). A related structure has been reported previously (Rubčić et al., 2008).
The components of the salt, (I), are illustrated in Fig. 1. With respect to the central hydroxybenzene ring in the cation, the phosphonium-P atom lies in a position almost perpendicular to the ring with the P1—C19—C20—C21 being -100.9 (3)°. On the other side, the hydrazone residue is twisted out of the central plane, with the C25—C24—C26—N1 torsion angle = 13.1 (4)°. The terminal fluorobenzene ring is significantly twisted out of the plane through the adjacent thiourea residue forming a dihedral angle of 51.69 (10)°. The configuration about the C26═N1 bond [1.281 (4) Å] is E. While the O—H and N—H hydrogen atoms are syn, in the thiourea residue, the N—H hydrogen atoms are anti. The latter allows for the formation of an intramolecular N—H···N hydrogen bond, Table 1.
The crystal packing features centrosymmetric {···HNCS}2 synthons, Table 1. Two Cl- anions are linked to the resulting dimeric aggregates via O—H···Cl hydrogen bonds, with the neutral four component aggregates linked into the three-dimensional architecture by C—H···Cl interactions, Fig. 2 and Table 1. Globally, the
comprises rows of hydrogen bonded thiourea residues sandwiched by the hydrazone and phosphonium substituents, with the sandwiches stacking along the a axis, Fig. 3.For the

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > 2σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

As part of efforts in improving the water solubility and biological properties of thiosemicarbazones (Kalinowski et al., 2009; Beraldo & Gambino, 2004), we report herein a new thiosemicarbazone molecule characterized as its Cl- salt, (I), containing a cationic triphenylphosphonium moiety, which is known to exhibit biological properties (Shahabadi et al., 2010). A related structure has been reported previously (Rubčić et al., 2008).
The components of the salt, (I), are illustrated in Fig. 1. With respect to the central hydroxybenzene ring in the cation, the phosphonium-P atom lies in a position almost perpendicular to the ring with the P1—C19—C20—C21 being -100.9 (3)°. On the other side, the hydrazone residue is twisted out of the central plane, with the C25—C24—C26—N1 torsion angle = 13.1 (4)°. The terminal fluorobenzene ring is significantly twisted out of the plane through the adjacent thiourea residue forming a dihedral angle of 51.69 (10)°. The configuration about the C26═N1 bond [1.281 (4) Å] is E. While the O—H and N—H hydrogen atoms are syn, in the thiourea residue, the N—H hydrogen atoms are anti. The latter allows for the formation of an intramolecular N—H···N hydrogen bond, Table 1.
The crystal packing features centrosymmetric {···HNCS}2 synthons, Table 1. Two Cl- anions are linked to the resulting dimeric aggregates via O—H···Cl hydrogen bonds, with the neutral four component aggregates linked into the three-dimensional architecture by C—H···Cl interactions, Fig. 2 and Table 1. Globally, the crystal structure comprises rows of hydrogen bonded thiourea residues sandwiched by the hydrazone and phosphonium substituents, with the sandwiches stacking along the a axis, Fig. 3.
