The Crystal and Molecular Structure of N1-Cyclohexyl-N2-(o-Chlorobenzal) Imino Thiourea

N1-Cyclohexyl-N2-(o-chlorobenzal) imino thiourea, C14H18 N3SCl, crystallizes in C2/c, with a=19.68, b=7.74, c=20.42angstrom, beta=92.8o and eight formula units in the unit cell. The structure was solved by the study of Patterson sections, calculated from three-dimensional film data, and was refined by block-diagonal least-squares methods to R=0.16 based on 1288 independent intensity data. The rest atoms of N1-Cyclohexyl-N2-(o-chlorobenzal) imino thiourea molecule excluding cyclohexan ring and chlorine atoms approximately lie on a plane. A pair of molecules related by the symmetry centers are connected directly with the N-H...... S hydrogen bonds. Apart from the hydrogen bonding system the structure is held together by the van der Waals forces.
