In this article, we assign Y(4274) to the color octet–octet type axialvector molecule-like state with tentatively, and construct the color octet–octet type axialvector current to study its mass and width with the QCD sum rules in details. The predicted mass favors assigning the Y(4274) to a color octet–octet type molecule-like state, but the predicted width strongly disfavors assigning the Y(4274) to the color octet–octet type molecule-like state. The Y(4274) may be the conventional charmonium state , and it is important to observe the decay to diagnose the nature of Y(4274).
