Abstract
We propose an integrable open XXZ chain coupled to the boundary impuri ties with arbitrary exchange constants. The Bethe ansatz equation and eigenvalues are obtained by using the quantum inverse scattering metho d. The ground-state properties are discussed by solving the Bethe equa tion in some special cases. In addition, we present an approach for co nstructing the reflecting matrix K which produces the boundary term co upled to impurities.
