AbstractThe title compound 1-(2-chlorophenyl)-3,3-bis(methylthio)prop-2-en-1-one (1) have been synthesized, crystallized and characterized using FT-IR, 1H NMR, 13C NMR, LCMS and confirmed by single crystal X-ray diffraction method. In addition, the intermolecular interactions in the crystal structure are analyzed using Hirshfeld surfaces computational method. The (1) crystallizes in a monoclinic crystal system (space group P 21/c) with cell parameters a = 17.0132(9) Å, b = 8.6521(4) Å, c = 8.2815(7) Å, β = 95.512(6) ° and Z = 4. Intermolecular hydrogen bonds/interactions of the type C · · · H · · · O, C–H · · · S, C–H · · · Cg and C–Cl · · · Cg stabilize the crystal structure. The intermolecular interactions responsible for crystal packing are analyzed using Hirshfeld surfaces computational method, 2D finger print plots, electrostatic potential surfaces, toplogy surfaces [curvedness (C) and shape index (S), enrichment ratio (E) and 3D energy frameworks]. In addition the dielectric studies were performed for the title molecule. The crystal structure database (CSD) analysis was carried out for structural conformation and crystal packing confirmation. Overall structural studies confirmed that the intermolecular interactions of the type S · · · S chalocogen bonds are involved in crystal packing in addition to the C11–H11 · · · O1, C10–H10B · · · O1, two C10–H10 · · · S1, C4–H11 · · · Cg1 and C1–Cl1 · · · Cg1 interactions.

Axis Orientation

Lipids containing long polymethylene chains were among the first compounds subjected to electron diffraction structure analysis. It was only recently realized, however, that various distortions of thin lipid microcrystal plates, e.g. bends, polar group and methyl end plane disorders, etc. (1-3), restrict coherent scattering to the methylene subcell alone, particularly if undistorted molecular layers have well-defined end planes. Thus, ab initio crystal structure determination on a given single uncharacterized natural lipid using electron diffraction data can only hope to identify the subcell packing and the chain axis orientation with respect to the crystal surface. In lipids based on glycerol, for example, conformations of long chains and polar groups about the C-C bonds of this moiety still would remain unknown.One possible means of surmounting this difficulty is to investigate structural analogs of the material of interest in conjunction with the natural compound itself. Suitable analogs to the glycerol lipids are compounds based on the three configurational isomers of cyclopentane-1,2,3-triol shown in Fig. 1, in which three rotameric forms of the natural glycerol derivatives are fixed by the ring structure (4-7).
