In this talk we summarize the results we obtained for the partial decay widths of ϕ(2170) into two-body final states formed by a K̄ and a Kaonic resonance, like K(1460), K1(1270), as well as to final states constituted by a ϕ and an η/η´ mesons. The results obtained are compared with the values extracted from experimental data on the corresponding branching ratios, which were determined by the BESIII collaboration. A reasonable agreement is found, which together with the previous reproduction of the mass, width, and cross section for the process e+e− → ϕ f0 strongly indicates the molecular nature of ϕ(2170) as a ϕKK̄ system.
