single-ion spin (S = 7/2) arising from the 4f7 electron configuration. (iv) Although MnIII ion possesses magnetic anisotropy due to Jahn-Teller distortion, it exhibit a comparatively high spin (S =2) and a large maximum entropy value calculated as Rln(2SMn + 1)/MMn = 271 Jkg-1K-1). In view of the above considerations compound 1 could be a good aspirant for magnetic coolers properties. The magnetic entropy changes (-ΔSm), that determine the magnetocaloric properties of 1, can be extracted from the experimental
