In the study of glassy network state interest among the experimenters and theorists is appraised in the analysis of structurally tangled state. Through a discussion of topological model, which are acquired to understand the atomic arrangement in the glass network we can recognise the technological relevance of chalcogenide glasses. Chalcogenide glasses relate to the (SnSe4)95-x (Bi2Te3)5+x (x = 0, 5, 15, 25, 35, 45 at %) alloy have been investigated for theoretical parameters. Based on average coordination number and the bond energies one should have estimated the average number of nearest neighbour of each type expected to embrace a given central atom. Using average coordination number <r> the various network parameters viz. bond stretching constant (Nα), bond bending constant (Nβ), total number of constraint per atom (Nc), lone pair of electron (L), of the glass alloy have been examined theoretically. Lone pair electron (L) value are found to be constant throughout the compositions as L value comes out to be greater than 3 indicates that alloy can retain their vitreous nature.The total number of constraint per atom (Nc) were calculated in the light of most stable composition which shows the best conditions for the glass formation.
