D=4, N=2 supergravity with Abelian electric and magnetic charges

We discuss the relation between standard N = 2 supergravity with translational gauging and N = 2 supergravities with scalar-tensor multiplets with massive tensors and abelian electric charges. We point out that a symplectic covariant formulation of N = 2 supergravity can be achieved just in the presence of tensor multiplets. As a consequence one can see that the formulation of the N = 2 theory as it comes from IIB flux compactification, which is included in these models, is equivalent to a non perturbative phase of standard N = 2 supergravity. It is also shown that the IIB tadpole cancellation condition is imposed by supersymmetry in four dimensions.
