The compound of selenium containing heterocycles namely (I) 4,6-dimethyl-3-cyanopyridine-(2H)-selenone (C8H8N2Se) was used as model to investigate the structural and micro-structural features of some selected selenones. Visualization of molecular structure of selenium containing moiety was accurately investigated to clarify role of selenium ion in nucleation process of forming 3D-framenet of H-bonded of substituted selenones. Bond distances, torsions on angles of investigated compound were compared with others crystal data to confirm crystal structures of substituted selenones which is monoclinic crystal form With P21/n space group.
