In this article, we assignY(4274) to the color octet–octet type axialvector molecule-like state withtentatively, 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 theY(4274) to a color octet–octet type molecule-like state, but the predicted width strongly disfavors assigning theY(4274) to the color octet–octet type molecule-like state. TheY(4274) may be the conventional charmonium state, and it is important to observe the decayto diagnose the nature ofY(4274).
