Abstract:For a finite group $ G$, let $ \Delta (G)$ denote the character graph built on the set of degrees of the irreducible complex characters of $ G$. In this paper, we show that if the diameter of $ \Delta (G)$ is equal to three, then the complement of $ \Delta (G)$ is bipartite. Also in this case, we determine the structure of the character graph $ \Delta (G)$.
