| Abstract: | The 3D framework Mn3(CH3COO)2(HCOO)4]n · nDMF ( 1 ) was obtained from the assembly of MnII ions with acetate and the in‐situ generated formate ligands. It features Mn‐centered MnMn4 tetrahedral nodes, each of which is linked to another four ones by sharing the apexes to form the 3D framework of 1 . Each of the acetate and formate ligands behaves as a syn‐syn:anti bridge to link two apical MnII ions and the central MnII ion. The magnetic measurement of 1 revealed the coexistence of spin‐canted antiferromagnetism and metamagnetism. It represents a typical example to synergistically use two kinds of carboxylate ligands to construct metal‐organic frameworks, as well as to tune the structure and magnetic properties of the aimed complex. |
