On computation of neighbourhood degree sum-based topological indices for zinc-based metal–organic frameworks

Abstract The permeable materials known as metal–organic frameworks (MOFs) have a large porosity volume, excellent chemical stability, and unique structure that results from the potent interactions between metal ions organic ligands. Work on synthesis, architectures, properties of various MOFs reveals their utility in variety applications, including energy storage devices with suitable electrode materials, gas storage, heterogeneous catalysis, assessment. A topological index, which is numerical invariant, predicts physicochemical entities based underlying molecular graph or framework. In this article, we consider two different zinc-based MOFs, namely zinc oxide silicate MOFs. We compute 14 neighbourhood degree sum-based indices for these frameworks, graphical representations all aforementioned are made.
