In this paper, we focus on the forming microwave induced phase grating (MIPG) in a crystal of molecular magnets. Firstly, we calculate the energy split of molecular magnet in the present of dc magnetic filed, and the results show that the frequencies dependence of the dc magnetic field are in the microwave frequency range. Secondly, the molecular magnet is subject two strong control magnetic fields (standing wave field and pump magnetic field). When a weak probe magnetic field with the frequency in the microwave range enters the crystal, the two control magnetic fields will modify the transmission and reflection properties of weak magnetic field. The system achieves high transmissivity and a big phase excursion for the weak probe magnetic field and form a microwave phase grating. Under proper parameters condition, the first-order diffraction efficiency of the microwave phase grating reaches 31%, which is close to an ideal sinusoidal phase grating. And the diffraction efficiency of the grating can be adjusted efficiently by tuning the control field intensity, interaction length L and the single photon detuning. Thirdly, we also discuss the effect of Dopper effect on the microwave phase grating.
