The 3D framework [Mn 3 (CH 3 COO) 2 (HCOO) 4 ] n · n DMF ( 1 ) was obtained from the assembly of Mn II ions with acetate and the in‐situ generated formate ligands. It features Mn‐centered MnMn 4 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 Mn II ions and the central Mn II 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.
