In the 10-dimensional framework of beta-supergravity, we characterize (4+6)-dimensional vacua preserving supersymmetry. We rewrite Killing spinor equations with NSNS non-geometric fluxes using the language of SU(3)*SU(3) structures and Generalized Complex Geometry, in analogy to standard type II supergravities. The NSNS generalized differential operator D that appears exhibits interesting properties, among which being a Generalized Dirac operator. This formulation leads us to a general expression for the superpotential, and we successfully compare it to existing formulas in the literature.
