In the framework of the one-boson-exchange model, we have studied the interaction of the B*(B) over bar and B*(B) over bar* systems. After considering the S-wave and D-wave mixing, we notice that both Z(b)(10610)(+/-) and Z(b)(10650)(+/-) can be interpreted as the B*(B$) over bar and B*(B) over bar* molecular states quite naturally. The long-range one-pion-exchange force alone is strong enough to form these loosely bound molecular states, which ensures the numerical results are quite model independent and robust.
