In the absence of background fluxes and sources, compactifying string theories on Calabi-Yau three-folds leads to supersymmetric solutions. Turning on fluxes, e.g. to lift the moduli of the compactification, generically forces the three-fold to break the Calabi-Yau conditions, and instead fulfill the weaker geometrical condition of having a reduced structure group. In this talk I will demonstrate that three-dimensional smooth, compact, toric varieties can have reduced structure group, and thus be suitable for flux compactifications of string theory. Since the class of three-dimensional SCTV is large, this is promising for the construction of new, phenomenologically interesting string theory vacua.
