Two fluorophosphates K2Mn(PO3F)F3 (1) and Na2Mn(HPO4)F3 (2) were synthesized through a hydrothermal method. It was found that 1 and 2 crystallize in the monoclinic space group of P21/c and P21/m, respectively, both exhibiting a uniform chain structure formed by MnO2F4 octahedra with corner-sharing F atoms along the b-axis. Magnetic and heat capacity measurements confirm that both compounds possess a short-range magnetic ordering at ~50 K and a long-range antiferromagnetic ordering below 15 K, showing their closing intra-chain exchange interactions, where the magnetic entropy change for such antiferromagnetic ordering can be estimated to be 0.19 J mol-1 K-1 for 1 and 0.29 J mol-1 K-1 for 2, respectively.
