Compensation points of The mixed spin-3/2 and spin-5/2 Ising ferrimagnetic system with different sublattice crystal- fields is studied within the mean-field theory based on Bogoliubov inequality for the Gibbs free energy. In order to clarify the characteristic behaviours in a series of molecular-based magnets, for example, the molecular magnetic material . The influence of two sublattice crystal fields, DA and DB, on compensation points is studied in detail. For certain crystal-field values, this mixed-spin model exhibits one, two or three compensation temperature depending on the values of the crystal-fields.
