    • The process e(+)e(-) -> phi eta' has been studied for the first time in detail using data sample collected with the BESIII detector at the BEPCII collider at center of mass energies from 2.05 to 3.08 GeV. A resonance with quantum numbers J(PC) = 1(--) is observed with mass M = (2177.5 +/- 4.8(stat) +/- 19.5(syst))MeV/c(2) and width Gamma = (149.0 +/- 15.6(stat) +/- 8.9(syst)) MeV with a statistical significance larger than 10 sigma, including systematic uncertainties. If the observed structure is identified with the phi(2170), then the ratio of partial width between the phi eta' by BESIII and phi eta by BABAR is (B-phi eta(R)Gamma(R)(ee))1(B-phi eta'(R)Gamma(R)(ee)) = 0.23 +/- 0.10(stat) +/- 0.18(syst), which is smaller than the prediction of the s (s) over barg hybrid models by several orders of magnitude.
