Let N be a simply connected, connected real nilpotent Lie group of finite dimension n. We study subgroups Γ in \Aff (N)=N\rtimes \Aut (N) acting properly discontinuously and cocompactly on N. This situation is a natural generalization of the so-called affine crystallographic groups. We prove that for all dimensions 1≤ n≤ 5 the generalized Auslander conjecture holds, i.e., that such subgroups are virtually polycyclic.
