%0 Journal Article %T Topological Characterization of the Crystallographic Structure of Titanium Difluoride and Copper (I) Oxide %J Atoms | An Open Access Journal from MDPI %D 2019 %R https://doi.org/10.3390/atoms7040100 %X Owing to their distinguished properties, titanium difluoride (TiF 2) and the crystallographic structure of Cu 2O have attracted a great deal of attention in the field of quantitative structure¨Cproperty relationships (QSPRs) in recent years. A topological index of a diagram (G) is a numerical quantity identified with G which portrays the sub-atomic chart G. In 1972, Gutman and Trinajsti£¿ resented the first and second Zagreb topological files of atomic diagrams. In this paper, we determine a hyper-Zagreb list, a first multiple Zagreb file, a second different Zagreb record, and Zagreb polynomials for titanium difluoride (TiF 2) and the crystallographic structure of Cu 2O.
