We look into the newly observed state from the molecular perspective in which the resonance is generated from the 
, 
and 
channels. We find that this picture provides a natural explanation of the properties of the state. We stress that the molecular nature of the resonance is revealed with a large coupling of the to the channel, that can be observed in the 
decay which is incorporated automatically in our chiral unitary approach via the use of the spectral function of 
in the evaluation of the loop function.
