N2 - The process e+e-→φη is studied at 22 center-of-mass energy points (s) between 2.00 and 3.08 GeV using 715 pb-1 of data collected with the BESIII detector. The measured Born cross section of e+e-→φη is found to be consistent with BABAR measurements, but with improved precision. A resonant structure around 2.175 GeV is observed with a significance of 6.9σ with mass (2163.5±6.2±3.0) MeV/c2 and width (31.1-11.6+21.1±1.1) MeV, where the first uncertainties are statistical and the second are systematic.
