A molecular (chemical) graph is a simple connected graph, where the vertices represent the compound’s atoms and the edges represent bonds between the atoms, and the degree (valence) of every vertex (atom) is not more than four. In this paper, we determine the edge metric basis and edge metric dimension (EMD) of the complex molecular graph of a one-heptagonal carbon nanocone ( $HCN_{7}(q)$ ). We prove that only three non-adjacent vertices are the minimum requirement for the identification of all the edges in $HCN_{7}(q)$ , uniquely.
