1,5-Bis[(E)-1-(2-hydroxyphenyl)ethylidene]carbonohydrazide dimethyl sulfoxide solvate

Abstract

The title dimethyl sulfoxide (DMSO) solvate, C17H18N4O3·C2H6OS, shows the disubstituted urea derivative to adopt an almost planar geometry (r.m.s. deviation for non-H atoms = 0.132 Å); the mol­ecule has non-crystallographic twofold mol­ecular symmetry. This conformation is stabilized by two intra­molecular O—H⋯N hydrogen bonds. The components of the crystal are connected by N—H⋯O hydrogen bonds, whereby both amine H atoms are connected to a DMSO O atom, and C—H⋯O contacts involving the DMSO H and urea carbonyl atoms, forming a supra­molecular chain along the c axis. The chains associate via C—H⋯π inter­actions.

1,5-Bis[(E)-1-(2-hydroxyphenyl)ethylidene]thiocarbonohydrazide monohydrate

“…The thiourea derivative in (I) is effectively planar with the maximum deviation of any of the torsion angles from 0 or 180° being 4.6 (2)° for N4-C10-C12-C13 and Table 1. Allowing for substitution of the thione by a ketone group, the described molecular conformation for the thiourea molecule in (I) resembles that in the recently reported ketone derivative (Zukerman-Schpector et al, 2009). 3.7821 (10) Å, with a dihedral angle between the least-squares plane through the rings of 2.25 (7)°; symmetry operation i:…”

“…Additionally, two intermolecular H⋯π interactions are noted,15 which add force to the crystal structure just described forming an helicoidal chain motif in c direction [HB7, r(H8A⋯R C2 ) = 2.66; HB8, r(R C2 ⋯H16B) = 2.74 Å].…”
