摘要：
Let G be a graph. The eccentric connectivity index xi(G) is defined as xi(G) = Sigma(u is an element of V(G))deg(u)epsilon(u) where deg(u) denotes the degree of vertex u and epsilon(u) is the largest distance between u and any other vertex v of G. In this paper, exact formulas for the eccentric connectivity index of one pentagonal carbon nanocones are given.
