Abstract

Metal-organic networks (MONs) are among the unique complex and porous chemical compounds. So, these chemical compounds consist of metal ions (vertices) and organic ligands (edges between vertices). These networks represent large pore volume, extreme surface area, morphology, excellent chemical stability, highly porous and crystalline materials, and octahedral clusters. MONs are mostly used in assessment of chemicals, gas and energy storage devices, sensing, separation and purification of different gases, heterogeneous catalysis, environmental hazard, toxicology, adsorption analysis, biomedical applications, and biocompatibility. Recently, drug delivery, cancer imaging, and biosensing have been investigated by biomedical applications of zinc-related MONs. The versatile applications of these MONs make them helpful tools in many fields of science in recent decade. In this paper, we discuss the two different zinc oxide and zinc silicate related MONs according to the number of increasing layers of metal and organic ligands together. We also compute the connection-based Zagreb indices such as first Zagreb connection index (ZCI), second ZCI, modified first ZCI, modified second ZCI, modified third ZCI, and modified fourth ZCI. Moreover, a comparison is also included between the zinc-related MONs by using numerical values of connection-based Zagreb indices. Finally, we conclude that zinc silicate-related MON is better than zinc oxide-related MON for all values of n.

Highlights

Metal-organic networks (MONs) are among the unique complex and porous chemical compounds
Eddaoudi et al [8] synchronized the isoreticular series (IRMOF-1 to IRMOF-16) of 16 highly crystalline materials. e free and fixed diameter of pores from IRMOF-1 to IRMOF-16 varies in the range of 3.8–19.1 and 12.8–28.8, respectively. e design of an IRMOF-10 series based on MON-5 was initiated by determining the reaction conditions necessary to produce the octahedral cluster with a ditopic linear carboxylate. erefore, many IRMOF structures can be developed by using zinc oxide octahedral clusters (Zn4O(CO)2) as the metal corners linked via diverse organic dicarboxylate linkers and different three-dimensional cubic networks are formed
We compute the main results for first Zagreb connection index (ZCI), second ZCI, modified first ZCI, modified second ZCI, modified third ZCI, and modified fourth ZCI of zinc oxide-related MON (ZNOX (n))
