The Crystal and Molecular Structure of 4-Formylimidazoline-2-thione

The title compound is monoclinic, space group P2 Jc, with a = 4.020 (4), b = 21.491(3), c = 7-410 (4) ,4,, fl = 124.1 (5) °, Z = 4. The structure was solved by Patterson-function and heavy-atom methods from diffractometer X-ray data. The final R value is 0.040. All the atoms lie approximately on the least-squares plane of the imidazoline ring. The molecules related by the glide plane are linked by N-H... O hydrogen bonds (2.840 ,~) to form a chain along e. The chains are held together by N-H... S hydrogen bonds (3.260 A) between the molecules related by an inversion centre.
