  The study of hadronic parameters of mesons is of great importance for
understanding the nature of strong interactions and QCD vacuum. One of the
approaches to investigate these properties is the QCD Sum Rule Method (QCDSR),
which has been extensively used for studying masses, decay constants, form
factors, decay widths, and so on properties of both traditional and exotic
hadrons. Recently BESIII collaboration discovered a new particle with a
statistical significance greater than 8{\sigma} in the hidden-charm channel of
the e^+ e^- annihilation, denoted as Y(4500). In this study, we investigate the
Y(4500) state in the framework of the QCDSR, assuming this particle is a
molecular state with quantum numbers J^PC=1^(--). We examined the two-point
correlation function and we take into account non-perturbative contributions in
OPE side evaluating up to operator dimension 10. We calculate the mass and
decay constant of the Y(4500) state and obtain a mass value consistent with the
results in the literature. We hope the studies presented in this paper provide
new insights to establish the hidden-charm molecular spectrum.
