摘 要：Due to the combinatorial nature of graphs they are used easily in pure sciences and social *** dynamical arrangement of vertices and their associated edges make them flexible(like liquid)to attain the shape of any physical structure or phenomenon *** the field of ICT they are used to reflect distributed component and communication among *** chemistry is another interesting domain of applied mathematics that endeavors to display the structure of compounds that are formed in result of chemical *** area attracts the researchers due to its applications in theoretical and organic *** also inspires the mathematicians due to involvement of mathematical *** or irregular bonding ability of molecules and their formation of chemical compounds can be analyzed using atomic valences(vertex degrees).Pictorial representation of these compounds helps in identifying their properties by computing different graph invariants that is really considered as an application of graph *** paper reflects the work on topological indices such as ev-degree Zagreb index,the first ve-degree Zagrebindex,the first ve-degree Zagrebindex,the second ve-degree Zagreb index,ve-degree Randic index,the ev-degree Randic index,the ve-degree atom-bond connectivity index,the ve-degree geometric-arithmetic index,the ve-degree harmonic index and the ve-degree sum-connectivity index for crystal structural networks namely,bismuth tri-iodide and lead *** this article we have determine the exact values of ve-degree and ev-degree based topological descriptors for crystal networks.
