                      J/ψπ$^{+}$π$^{−}$K$^{+}$K$^{−}$ are studied using a
                      data set corresponding to an integrated luminosity of 9
                      fb$^{−1}$, collected with the LHCb detector in
                      proton-proton collisions at centre-of-mass energies of 7, 8
                      and 13 TeV. The decays $ {\mathrm{B}}_{\mathrm{s}}^0 $ → $
                      \mathrm{J}/{\psi \mathrm{K}}^{\ast
                      0}{\overline{\mathrm{K}}}^{\ast 0} $ and $

                      χ$_{c1}$(3872)K$^{+}$K$^{−}$, where the
                      K$^{+}$K$^{−}$pair does not originate from a ϕ meson, are
                      observed for the first time. Precise measurements of the
                      ratios of branching fractions between intermediate
                      χ$_{c1}$(3872)ϕ, $ \mathrm{J}/{\psi \mathrm{K}}^{\ast
                      0}{\overline{\mathrm{K}}}^{\ast 0} $, ψ(2S)ϕ and
                      χ$_{c1}$(3872)K$^{+}$K$^{−}$ states are reported. A
                      structure, denoted as X(4740), is observed in the J/ψϕ
                      mass spectrum and, assuming a Breit-Wigner parameterisation,
                      its mass and width are determined to be$ {\displaystyle
                      \begin{array}{c}{m}_{\mathrm{X}(4740)}=4741\pm 6\pm
                      6\kern0.5em \mathrm{MeV}/{c}^2,\\

                      \mathrm{MeV},\end{array}} $where the first uncertainty is
                      statistical and the second is systematic. In addition, the
                      most precise single measurement of the mass of the $
                      {\mathrm{B}}_{\mathrm{s}}^0 $ meson is performed and gives a
                      value of$ {m}_{{\mathrm{B}}_{\mathrm{s}}^0}=5366.98\pm
