Abstract
The second multiplicative Zagreb coindex of a simple graph $G$ is defined as: $${overline{Pi{}}}_2left(Gright)=prod_{uvnotin{}E(G)}d_Gleft(uright)d_Gleft(vright),$$ where $d_Gleft(uright)$ denotes the degree of the vertex $u$ of $G$. In this paper, we compare $overline{{Pi}}_2$-index with some well-known graph invariants such as the Wiener index, Schultz index, eccentric connectivity index, total eccentricity, eccentric-distance sum, the first Zagreb index and coindex and the first multiplicative Zagreb index and coindex.
