Abstract: Examples are constructed of rationally isomorphic, finitely generated nilpotent groups $L$

and

such that there are no homomorphisms $L \rightarrow M, M \rightarrow L$ inducing rational isomorphisms. Similar examples are constructed of nilpotent, or even simply-connected, finite CW-complexes.
