Conventional (MCE) and rotating (RMCE) magnetocaloric effects have been explored in the two-dimensional (2D) coordination polymer {(tetren)-H-5)(0.8)Cu-4(II)[W-V(CN)(8)](4)center dot 7.2H(2)O}(n) (WCu-t; tetren = tetraethy-lenepentamine). The unusual magnetostructural properties were exploited, including the bilayered Prussian Blue like coordination skeleton and the XY easy-plane magnetic anisotropy based on the in-plane correlation between W-v and Cu-II spins of 1/2, underlying the Berezinskii-Kosterlitz-Thouless (BKT) topological phase transition to the long-range -ordered state at T-c = 33 K. The magnetic properties were studied on single crystals along the H parallel to ac Mac easy plane and H parallel to b hard axis. The maximal entropy change for MCE for easy-plane geometry at 38.0 K and the magnetic field change mu(0)triangle H = 7.0 T reached similar to 4.01 JK(-1) kg(-1). The strong magnetic anisotropy was used to study the RMCE in which the maximal entropy change was observed at 35.5 K for 7.0 T, attaining 1.81 JK(-1) kg(-1). Moreover, easy-plane anisotropy introduces the inverse magnetocaloric effect for H parallel to b, which enhances the RMCE by up to 47%. This observation was confirmed by a theoretical investigation considering the XY model using a molecular field and cluster variational method in the pair approximation approach; dedicated to the bilayered systems with the adequate nearest neighbor number z = 5 and spin S = 1/2.
