N1 - Funding information: The first author is member of the SFB/TR 45. During parts of this project, the second author was supported by the DFG Emmy Noether-Nachwuchsgruppe “Gute Strukturen in der höherdimen-sionalen birationalen Geometrie” and thereby also member of the SFB/TR 45. We thank D. Kotschick for detailed comments and P. Cascini, M. Land, E. Sernesi, R. Svaldi and B. Totaro for conversations.

N2 - We show that many spin 6-manifolds have the homotopy type but not the homeomorphism type of a Kähler manifold. Moreover, for given Betti numbers, there are only finitely many deformation types and hence topological types of smooth complex projective spin threefolds of general type. Finally, on a fixed spin 6-manifold, the Chern numbers take on only finitely many values on all possible Kähler structures.
