On Reverse Valency Based Topological Indices of Metal–Organic Framework

Abstract

Metal–organic frameworks (MOFs) are penetrable materials created by very strong bonds between metal ions and organic ligands to perform very high surface area, large pore volume, attractive chemical stability, and erratic morphology. Work on characteristics, synthesis, and structures of many MOFs manifest the significance of these frameworks with adaptable applications, such as energy storage devices of excellent electrode materials, gas storage, heterogeneous catalysis, environmental hazard, evaluation of chemicals, sensing of distinct gases, conducting solids, and super-capacitors. Topological descriptors are numerical quantity that are used to design various physical, medical, chemical, and pharmacological properties of molecular compounds. It is very fascinating to study the molecular topology that contributes a basis for correlation of physicochemical property of a well-defined molecule. Reverse degree-based topological indices play important role for calculation of topological descriptor. In this article, we give explicit expression of the reverse general Randic index, the reverse atom bond connectivity index, the reverse geometric arithmetic index, the reverse forgotten index, the reverse augmented index, and different types of reverse Zagreb indices of the MOF butylated hydroxytoluene (BHT)- based metal–organic (M = Co, Fe, Mn, and Cr) (MBHT) frameworks. A comparison between the calculated different types of the reverse degree-based topological indices with the aid of the numerical values and their graphs is also included.
