We discuss type II theories in space-time backgrounds that admit an SU(3) structure. We will see that the couplings strongly resemble those of four-dimensional N=2 supergravity. Specifically, we show that the moduli space of metrics are special Kahler manifolds with Kahler potentials given by the Hitchin functionals. We also compute the N=2 version of the superpotential in this language, and find its N=1 counterpart.
