Abstract The beauty hadron decays is unique laboratory to study charmonium and charmonium-like states, such as the χc1(3872) meson, other exotic states and the tensor D-wave Ψ2(3823) states. However the nature of many exotic charmonium-like candidates are still unknown. The most recent LHCb results related to b-hadron decays to charmonium states and obtained using large data samples collected during the Run 1 and Run 2 periods are presented. This includes the most precise determination of the mass and width of the χc1(3872) state using the B+J/ψπ+πK+ decays, observation of a resonant structure denoted as X(4740) in the Jψϕ mass spectrum from Bs0J/ψπ+πK+K decays and the precise measurement of the Bs0~meson mass.
