By using Monte Carlo simulation based on the Metropolis algorithm, we investigate the dynamic magnetic properties of a ferrimagnetic mixed (2, 5/2) Ising spin monolayer nanographene structure with a crystal-field interaction in a time oscillating magnetic field. We obtain dynamic phase transitions, and we discuss the effect of the next-nearest neighbor interactions, the crystal field, the amplitude, and the period of the external dynamic magnetic field on the critical behavior and on the thermal variations of the dynamic order parameters. We show that the system exhibits a dynamic first- and second-order phase transitions, the dynamic tricritical points, the dynamic critical end-point, and the dynamic compensation points.
