Two three-dimensional (3D) coordination polymers, namely MnII6(CH3COO)2(HCOO)2(IN)8(C4H8O)2(H2O) and MnIII6MnII12(μ3-O)6(CH3COO)12(IN)18(H2O)7.5 (abbreviated as MnII6 and MnII12MnIII6 respectively; HIN = isonicotinic acid), were synthesized by the reaction of Mn(CH3COO)2·4H2O and isonicotinic acid under solvothermal conditions. Magnetic studies revealed that antiferromagnetic interactions may be present in compounds MnII6 and MnII12MnIII6. Moreover, the values of −ΔSm (26.27 (MnII6) and 37.69 (MnII12MnIII6) J kg−1 K−1 at ΔH = 7 T) are relatively larger than those of the reported Mn-based coordination polymers. This work provides a great scope in the magnetocaloric effect (MCE) of pure 3d-type systems.
