Abstract

A group of chemical compounds containing organic ligands and metal ions(clusters) called as Metal organic networks (MON s). These are found as one, two and three dimensional structures of porous and subordinate class of coordination polymers. The characteristics of MON s are high surface area, large pore volume, different morphology and very good chemical stability. The applications of MON s includes gas storage, heterogeneous catalysis and sensing of various gases. The stability and characteristics of these networks have become important because of the above said characteristics. The numerical invariants used to predict the physicochemical characteristics and bioactivities of chemical compounds known as topological indices. In our proposed work, we compute neighborhood redefined first Zagreb index, neighborhood redefined second Zagreb index and Generalized Reciprocal Sanskruti index for two different MON s.
