Furthermore, there are no two mesons of $s\\bar s$ available to form a molecule which fits the mass spectrum of $\\phi(2170)$, thus we suggest it should be an $ss\\bar s \\bar s$ tetraquark state. In this scenario, we estimate its decay rates through the fall-apart mechanism. Our theoretical estimates indicate that its main decay modes should be $\\phi(2170)$ into $\\phi f_0(980)$, $ h_1\\eta$, $ h_1\\eta'$, $K_1(1270)K$ and $K_1(1400)K$.
