title: A heterometallic strategy to achieve a large magnetocaloric effect in polymeric 3d complexes.
abstract: Metal formate frameworks [A][CrMn(HCOO)6] (A = CH3NH2CH3(+) for 1 and CH3NH3(+) for 2) with a large MCE were obtained, directed by the heterometallic strategy in which very weak magnetic interactions were achieved. A switch from antiferromagnetism to ferromagnetism occurs when replacing the CH3NH2CH3(+) cation with CH3NH3(+). The magnetic entropy change (-ΔSm) reached 48.20 J kg(-1) K(-1) for 2, which is the largest among the known polymeric 3d complexes.
