The aim of this paper is focusing on $\eta$-Einstein geometry of complex contact metric manifolds. We give the definition of complex $\eta$-Einstein normal complex contact metric manifolds. In addition, we study on Weyl conformal curvature tensor $\mathcal{W}$ and concircular curvature tensor $\mathcal{Z}$ and we show that a normal complex contact metric manifold which satisfy $\mathcal{Z}\left( U,X\right) .\mathcal{W}=0$ and $\mathcal{Z}\left( V,X\right). \mathcal{W}=0$ complex $\eta$-Einstein. Also, we prove that a projectively semi-symmetric normal complex contact metric manifold is complex $\eta$-Einstein.
