  The heavy quark spin symmetry implies that in addition to the recently
observed Z(10610) and Z(10650) molecular resonances with $I^G=1^+$ there should
exist two or four molecular bottomonium-like states with $I^G=1^-$. Properties
of these G-odd states are considered, including their production in the
radiative transitions from Upsilon(5S), by applying the same symmetry to the
Upsilon(5S) resonance and the transition amplitudes. The considered radiative
processes can provide a realistic option for observing the yet hypothetical
states.
