Synthesis and structure determination of 7a-Aza-B-homostigmast-5-eno [7a, 7-d] tetrazole-3β-yl chloride (C29H47N4Cl)

7a-Aza-B-homostigmast-5-eno [7a, 7-d] tetrazole-3β-yl chloride (C29H47N4Cl) was synthesized for its crystallographic analysis and to investigate the role of intraand intermolecular interactions in steroids. It crystallizes in the monoclinic space group C2 with unit cell parameters: a= 38.481(2), b= 6.661(3), c= 11.111 (6) A, β = 94.49 (4)o; λ( MoKα)= 0.71069 A, V= 2839(2) A3, and Z= 4. The structure has been solved by direct methods using X-ray diffraction techniques. The final reliability index for the computed structure is 0.0597 for 1252 observed reflections. Except the five-membered ring, all other rings of the steroid nucleus exist in non-planar conformations. The structure is stabilized by C–H···N intermolecular interaction.
