It is suggested that the newly observed Y(4260) by BARBAR collaboration is a molecular state composed of an omega and a chi_{c1}. Both the production and decay properties are discussed. A consequence for this molecular state, Y(4260), is that it decays into pi+pi-pi0 chi_{c1} with similar rate to pi+ pi- J/psi. It is also expected that Y(4260) -> pi0 pi0 J/psi is produced at half rate as Y(4260) ->pi+ pi- J/psi. These decay modes should be searched for in the B factories using initial state radiative return data and B decay data as well.
