L-valine is considered one of the essential amino acids for mammals, which belongs to the glycogen types of amino acids. This amino acid is valuable for making protein. Due to the diverse structure of N-salicylidene-L-valine and its higher catalytic and cytotoxic activity it gains impressive interest. To study this structure more deeply and to know more about its properties in terms of topological indices, we study the supramolecular chain in dialkyltin of complex- 2 , 3 , and 4 of N-salicylidene-L-valine. In the end, we provide a comparative study of these structures by taking particular examples and also gives a comparison between topological indices. [ABSTRACT FROM AUTHOR]

In this paper, we discuss the degree based topological properties of the novel planar metal-organic networks TM – TCNB. Interestingly, the TM – TCNB systems are metallic in any event in one turn heading and show long-run ferromagnetic coupling on the off chance that for attractive structures, which speak to perfect applicants and a fascinating possibility of uncommon applications in spintronics. Chemical graph theory plays an important role in modeling and designing any chemical structure. The topological indices are the numerical invariants of a molecular graph and are very useful for predicting their physical properties. We have computed the degree based topological indices for this metal-organic networks TM – TCNB. [ABSTRACT FROM AUTHOR]

Sierpiński graphs are frequently related to fractals, and fractals apply in several fields of science, i.e., in chemical graph theory, computer networking, biology, and physical sciences. Functions and polynomials are powerful tools in computer mathematics for predicting the features of networks. Topological descriptors, frequently graph constraints, are absolute values that characterize the topology of a computer network. In this essay, Firstly, we compute the M-polynomials for Sierpiński-type fractals. We derive some degree-dependent topological invariants after applying algebraic operations on these M-polynomials.
